Hey Everyone, hope you like my growing post :). Just to let you know:Pink= The Questions askedBlack= The InformationRed= Example QuestionsBlue= The work shown for each Example Question*Colour may vary Question #1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples. The Pythagorean Theorem was developed by a Greek mathematician, Pythagoras. The Pythagorean Theorem is used to find lenghts of the sides of any right triangle. Area of a square = length x widthPythagoras treated each sides of a right triangle as though it were a square and discovered that the total area of the two smaller squares then wrote his discovery as a formula.Two special triangles Isosceles right triangle So what is the formula that Pythagoras came up with? Well, its simple : use the formula to find the hyponuse or either two of the legs.The picture above: is of Pythagoras on snoopy's body teaching William Hung about the Pythagorean Theorem. *William Hung was not alive at the time of Pythagoras just so you know!1)A right triangle has a hypotenuse or 30 and a base of 20 what is the missing leg? 2) A right triangle has a base of 5 and a leg or 15, what is the missing hypotenuse? Question #2: How do you find the surface area of a right rectangular prism? You should use words, pictures, symbols and numerical examples. A rectangular prism is a three dimentional shape where all the sides are rectangles and all sides meet perpendicularly. The bases are congruent with eachother. Cereal boxes and bricks are rectangular prisms. To find the surface area of the examples above: the cereal box and the brick. Measurments will have to me made. Plug the measurements into the formula and solve. To the left, is an example of a rectangular prism. and examples of its length and height which are important when solving for volume and surface area.To find Surface area, use the following formula: SA=2(l*w)+2(l*h)+2(h*w) The formula for finding Volume:V=l*w*hExample of Surface Area:A Rectangular Prism has a lenth of 23m a width/depth of 13m and a height of 12m. What is the surface area? Example of Volume: Find the volume of a rectangular prism if the length is 23 the width/depth is 13 and the height is 12. Surface area and Volume is helpful when it comes do designing a home, room, or painting a room or a whole house. Question #3: How do you find the surface area of a right cylinder? You should use words, pictures, symbols and numerical examples. A three dimentional shape made of parallel segments to a line of two parallel pnales conected to congruent bases that are circles in the planes. Examples include pillsbury crescents in a tube and some certain trash cans are cylinders.To find the surface area, first find the measurements then plug them into the formula and solve. To the right, is an example of cylinders with the radius which is extremely important to use when solving anything involving a cylinder or a circle.To find the Surface area of a right cylinder, use the formula: The formula may be hard to use at first, once it is used more often it will become familiar therefore making it memorized.Question #4: What is a polygon and how do we classify one?A polygon is a shape that is closed up that has at least around three lines. Regular polygons are made up of same symmetric lines, angles and length. Irregular polygons are made up of non symetric lines. Here on the right are some examples of a polygon. Ex. octagon, hexagon, decagon, nonagon, square and other shapes that is closed up.Shape are everywhere in the world! Dr. Pepper is a drink, that takes the shape of a cylinder, it has a length and a radius. By finding the measurements for the can, the circumference, diameter, and radius of the circles on the top and bottom can be foun[...]2007-05-10T06:35:43.468-07:00
Question 1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples. What is the Pythagorean Theorem? Well my friends, it’s a formula. The formula is a2 + b2 = c2 . That means altitude squared plus base squared is equal to the hypotenuse squared. The side that is opposite of the right angle is the hypotenuse. The base and altitude are the other two, but they’re also called legs. A= Altitude B=BaseC=Hypotenuse Now lets just say that A is 10 cm,B is 10 cm, and you're solving for c.Well you would go:a2 + b2 = c210 2 + 10 2 = c 2100 + 100 = c 2200√ = cc= 14.2Now we're solving for B instead of C ! Yes...quite intense. But, don't be scared, it's just as easy:) alrighty, so first try to think it out on ur own without looking at the answers............ okay, now I'll work you through it. So now since you are trying to figure out what B is, you would go C2-A2=B2.So we know that C is 9 and A is 8. So 9 squared is 81, 8 squared is 64, therefore we have 81 - 64 = C 2. Now, 17 = B 2. Then you get the square root of 17 ! which is 4.2 . And then BAM ! B = 4.2 CM !!! Its super fun once you get the hang of it ! :)Question 2: How do you find the surface area of a right recta ngular prism? You should use words, pictures, symbols and numerical examples.A right rectangular prism is a six sided rectangle with all right angles, like a cube, but longer. Now lets find the surface area. The formula is:SA= 2 ( L x W ) + 2 ( L x H ) + 2 ( W x H )soo.....SA= 2 ( 6 x 4 ) + 2 ( 6 x 6.5 ) + 2 ( 4 x 6.5 )SA= 2 (24) + 2 (39) + 2 (26)SA= 48 + 78 + 52SA= 178 cmHOW COOL ?! ;)Question 3: How do you find the surface area of a right cylinder? You should use words, pictures, symbols and numerical examples. A right cylinder is basically just a tube, with a circle on both ends, like a can, or a jar.The Formula is 2πR 2 + 2πRHThese lipsticks are all cylinders ! :) Question 4: What is a polygon and how do we classify one? A polygon is simply a shape made up of three or more straight lines that all connect. A regular polygon has sides that that are all the same size, and it has as many sides as vertices. An irregular polygon is just the opposite; sides with different lengths are angles. IT'S SIMPLE ![...]2007-05-09T20:40:49.522-07:00

Question 1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples. (10 Marks)2007-05-10T13:37:10.607-07:00
Question 1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples. A right angle triangle has a base, altitude, hypotenuse and a right angle.The Theorem of Pythagoras, (which was named after the famous mathematician Pythagoras), is a formula that is written as a² + b² = c². The a represents the altitude, the b represents the base and the letter c represents the hypotenuse.This formula states that the altitude squared, plus the base squared, equals the hypotenuse squared of a right angle triangle. (This formula only works on right angle triangles!)Now, let's solve an equation with a missing hypotenuse. Don't worry, if you use the formula correctly this equation should be easy.Let's solve one more equation, except this time, the equation will have a missing leg, (altitude or base), instead of the hypotenuse. This may seem tricky, but if you use your knowledge of algebra, it should be a piece of cake!Question 2: How do you find the surface area of a right rectangular prism? You should use words, pictures, symbols and numerical examples. You may not realize it, but we see right rectangular prisms everywhere during our everyday lives. Some examples include....Cereal BoxesSpeakersDVD PlayersJewellery BoxesYou can easily find the surface area of a right rectangular prism by using the following formula:SA = 2 (lw) + 2 (lh) + 2 (wh)This is a net of a right rectangular prism. When it is folded correctly, it creates a rectangular prism.Using the rectangular prism I made and its dimensions, let’s figure out its surface area.SA = 2 (l h) + 2 (h w) + (l w)SA = 2 (15 8) + 2 (8 5) + 2 (15 5)SA = 2 (120) + 2 (40) + 2 (75)SA = 240 + 80 + 150SA = 470 m²Question 3: How do you find the surface area of a right cylinder? You should use words, pictures, symbols and numerical examples. A cylinder is a solid that has two parallel, congruent circular bases. We actually see cylinders everywhere around us. Here are some examples of cylinders you might be familiar with:Soup CansFrozen JuicePop CansHere is a picture of a cylinder and its dimensions.This is what the cylinder above, would look like if it was flattened out. This is called the cylinders’ net.Finding the surface area of a cylinder is quite simple, if you use the correct formula. The formula is: SA = 2п r² + 2п r Using the same cylinder, let’s figure out how to find the surface area.SA = 2п r² + 2п r hSA = 2 (3.14) 5² + 2 (3.14) (5) (12)SA = 2 (3.14) 25 + 6.28 (60)SA = 157 + 376.8SA = 533.8 cm²Question 4: What is a polygon and how do we classify one?A polygon is classified as any closed figure that has three or more straight line segments. Chart of Polygons Having up to 10 Sides>There are two types of polygons, regular and irregular. An irregular polygon is classified as having angles of different sizes and sides of different lengths.Examples of Irregular Polygons This album is powered by BubbleShare - Add to my blog A regular polygon is classified as having sides of equal length and angles of the same size.Examples of Regular Polygons This album is powered by BubbleShare - Add to my blogNot Polygons This album is powered by BubbleShare - Add to my blog[...]2007-05-03T11:57:43.623-07:00

Question 1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples. (10 Marks)"A" stands for altitude, "B" stands for base, and "C" stands for hypotenuse.In this diagram, we do not know the measurement of C. To find C, we use the Pythagorean Theorum. The Pythagorean Theorum is that the altitude of a right triangle squared added to the base of a right triangle squared is equal to the hypotenuse of a right triangle squared. We do this:4.5 squared + 6 squared = C squared 20.25 + 36 = C squared56.25 = C squared Now, you have to find the square root of 56.25. Don't forget our algebra unit; what you do to one side you must do to the other.The square root of C squared is C.The square root of 56.25 is 7.5.The hypotenuse in this diagram is 7.5 meters.For this question, our altitude is missing. But we still use the Pythagorean Theoru. We do this :A squared + 6 squared = 10 squared A squared + 36 = 100A squared = 100 - 36A squared = 64Now we have the same last step as our first question, and we do the same thing. Figure out the square roots: The square root of A squared is A.The square root of 64 is 8.Therefore, the altitude of this right triangle is 8.Question 2: How do you find the surface area of a right rectangular prism? You should use words, pictures, symbols and numerical examples.(10 Marks)A right rectangular prism is a 6-sided rectangle with all right angles. To find out the surface area of a right rectangular prism, you must use this formula:2(LH) + 2(LW) + 2(HW) You use this formula because there are 6 sides, front, back, left, right, top, and bottom. The front and the back have the same height, lenght, and width, left and right have the same heigh, length, and width, and top and bottom have the same height, length, and width.These are two pictures of rght rectangular prisms that i found on the internet:Alright, to figure out the Surface Area of this net we will use this formula:2(LH) + 2(LW) + 2(HW)So, our problem should look like this:2(5x5) + 2(5x3) + 2(5x3)Now, we multiply:2(25) + 2(15) + 2(15)Again, we multiply:50 + 30 + 30Now all we have to do is add:110Our Surface Area is 110 meters.Question 3: How do you find the surface area of a right cylinder? You should use words, pictures, symbols and numerical examples. (10 Mark)To find the surface area of a right cylinder, you must use this formula:2(3.14 or pi) r squared + 2 (3.14 or pi) r h (r stands for the radius, h stands for height)The radius for this cylinder is 3 cm, the height 9 cm. Can you figure out how to do it?Well it doesnt matter if you can or not, cause i'm going to tell you anyway:)We do this:2(3.14) 3 squared + 2 ( 3.14) (3) (9) 2 (3.14) 9 + 2 (3.14) (3) (9)6.28 (9) + 6.28 (3) (9)56.25 + 18.84 (9)56.25 + 169.56SA = 225.81 cm squared What is a polygon and how do we classify one? (10 Marks)A regular polygon is a polygon whose sides are all the same and whose angles are all equal , whereas an irregular poygons sides are different in length and the angles are different measurements. To classify a polygon, you first need to know the exact definition of a polygon.Definition : any closed figure with 3 or more straight sides.The next step to classifying a polygon, would be to determine whether it is a regular or irregulat polygon, using the definitons above it shouldnt be too difficult. And then, your done classifying ! :)This picture below is an example of some classified polygons :[...]2007-05-18T09:34:54.162-07:00

Please enjoy my fantastic growing post! ;)Question 1: What is the Pythagorean Theorem?This album is powered by BubbleShare - Add to my blogQuestion 2: How do you find the surface area of a right rectangular prism?First off, a right rectangular prism has 6 faces (and the faces that are opposite of each other are of the same measurements). The surface area is simply the sum of the six sides. To find the surface of a rectangular prism you must follow the following formula: 2(l.w) + 2(l.h) + 2(w.h). And that's about it!Shortcut Lettersl = lengthw = widthh = heightAnd, you better believe me when I tell you that examples of rectangular prisms are in fact, microwave ovens and CD cases. Imagine life without them! We better be thankful for our ingenious inventions that have taken the shape of a 3D rectangles!For more help on surface area, check out this website!http://www.mathguide.com/lessons/SurfaceArea.html(Copy and paste into your browser!!)Question 3: How do you find the surface area of a right cylinder?I'm just going to throw it out there; a cylinder can come in all shapes in sizes (short, tall, skinny, wide) but the way of calculating the surface area is always the same for a right cylinder. 2 x π x r x r + 2 x π x r x hWith 'r' equaling radius, 'h' equaling hight and π equaling 3.14Below is my fabulous net and right cylinder diagram that has been prepared for you on gliffy! Please view it; it is very attractive and accurate!PLEASE NOTICE: Soup tins and batteries are perfect examples of cylinders. Although, the battery is a little deformed at each end, you get the idea. (: Question 4: What is a polygon and how do we classify one?A polygon is classified as a closed figure with three or more straight sides. A name of a particular polygon is determined by the number of sides it has. A regular polygon is classified by equal sides and same angles. An irregular polygon is classified by unequal angles and sides. (It would be the exact opposite of a regular Polygon!)Figure one, (above), shows regular polygons in purple and irregular in yellow.*** And remember, a polygon is always a polygon no matter how many sides it has! As long as the lines are straight and in the end, the figure is closed! (:[...]2007-06-07T11:23:10.639-07:00
