Picture and description:
The sides A and B are not more than C when they are put together, therefore the triangle is impossible.

This stands for base * height /2.

For example: A triangle has a base of 5 inches and a height of 5 inches. What is the area of the triangle?

The answer would be 12.5 square inches, because 5 * 5 is 25 and 25/2 is 12.5]]> 2018-04-14 16:46:03 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251807591 Area of rectangles mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251808566 To find the area of a rectangle or square, multiply the length and width together. This is also the reason the formula for the triangle works, because one triangle is half of a square.

For example: A rug has a length of 5 feet and a width of 2 feet. What is the area of the rug?

The answer is 10 square feet because 5 * 2 is 10.]]> 2018-04-14 16:57:58 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251808566 Area of circles mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251809381 The formula for the area of a circle is  π r2

For example: A fruit tart has a radius of 3 inches. What is it's area?

The answer would be 28.27 because pi times 3 squared is 28.27]]> 2018-04-14 17:06:55 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251809381 Surface area of a square pyramid mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251819222 To find the surface area of a square pyramid you find the area of one of the triangles, and multiply it by four. You also find the area of the base, which is a square.

For example: A square pyramid has a base that is 4 by 4 and each side has a height of 5. 

The base would be 16, and each of the sides would be 10. Since there are 4, all the sides together would be 40, which added with 16 is 56.]]> 2018-04-14 19:27:46 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251819222 Area of a trapezoid mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251877682 A=[(b1+b2)*h]/2
A is area, a is the smaller base, b is the larger base and h is the height.

For example a trapezoid has bases of 5 and 2, and a height of 3. What is it's area?

The area would be 10.5 because 5+2 is 7, which multiplied by 3 is 21. Then divided by 2 is 10.5.

C is circumference and r is radius.

It's circumference would be 18.85 because 2π3 is 18.85.]]> 2018-04-15 12:56:56 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251879812 Triangular prism surface area mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251880212 Like other surface area equations, you simply find the area of each side and add them all together. This shape is composed of 3 rectangles and 2 triangles with the same area. Therefore you find the area of each of the rectangles, and multiply the area of one of the triangles by two. Then you add them together.

For example: A triangular prism has a triangular face with a base of 4 and height of 3. It's rectangular face has a length of 15 and width of 5. 

The surface area would be 261 because 36 is the area of the triangles put together and the three rectangles would be 225.]]> 2018-04-15 13:01:23 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251880212 Rectangular prism surface area mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251880241 A rectangular prism is made up of  6 rectangles, 4 of the same area and 2 with another area. So you have to add area A * 4 and area B * 2.

For example: The area of one side of a rectangular prism is 24 and the area of another side is 4. What would the surface area be?

The surface area would be 104 because 24 x 4 is 96 and 4 x 2 is 8.]]> 2018-04-15 13:01:42 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/251880241 How to find the surface area of a cylinder mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/254066404 2πrh+2πr² is the formula for finding the surface area of a cylinder. 

In other words, you multiply the radius by pi and the height, and multiply that by 2. Then you find pi times the radius AGAIN square it, and multiply by 2.

For example: A cylinder has a height of 9 and radius of 3. What is it's surface area?

The answer would be 226.19.]]> 2018-04-21 17:01:33 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/254066404 Essential question 2 mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/254067346 What happens when the dimensions of a shape are changed?

The shape will increase or decrease by how much the dimensions are multiplied or divided by. 

If one of a square's sides is multiplied by 4 then the area of the square will multiply by 4 as well. If both sides are multiplied by 4, the area of the square will multiply by 8. If the radius of a circle is doubled the circle's area will double as well.]]> 2018-04-21 17:14:58 UTC https://padlet.com/mamorvan/c45qpb1n1cyr/wish/254067346 Volume of a sphere mamorvan https://padlet.com/mamorvan/c45qpb1n1cyr/wish/255423719 V=4/3πr3

To find the area of the outer shape that is not covered, simply find it's area and subtract the area of the inner shape.
For example: A square has a circle inscribed in it. The circle has a radius of 3 inches. What is the area of the square without the circle covering it?
It's area would be 7.73 inches²

A composite shape is 2 shapes that make up one shape. To find the area of one of these, find the area of each shape and add them together. 
For example: A shape is consisted of a triangle and a square. The square is 6 units by 6 units and the triangle has a height of 4 units and base of 6 units. What would the area of the whole shape be?
