Math Humor Write the expression for the volume of a thick crust pizza with height "a" and radius "z". Hint: To find the volume, multiply the area of the pizza by the height.

LT 9.4 Describe the effect on perimeter and area when one or more dimensions of a figure are changed.

In the graph, the height of each DVD is used to represent the number of DVDs shipped per year. However as the height of each DVD increases, the width also increases, which can create a misleading effect.

Find the original perimeter 28 Find the new perimeter if both sides are multiplied by 3 84 which is 28 x 3

Find the original area 40 Find the new perimeter if both sides are multiplied by 3 360 which is 40 x 9 or 40 x 3 2

Describe how the area changes if one dimension is changed Describe how the area changes if one dimension is changed. Height is multiplied by 6 30 in2 to 180 in2 so the area increased 6 times Describe the effect if both the base and height are multiplied by 6 30 in2 1080 in2 so the area increased 36 times or 62

When the dimensions of a figure are changed proportionally, the figure will be similar to the original figure.

Example 3 A circle has a circumference of 32 in. If the area is multiplied by 4, what happens to the radius? It is doubled b. An equilateral triangle has a perimeter of 21m. If the area is multiplied by 1 2 , what happens to the side length? Multiplied by 2 2

A square sandbox has an area of 16 square feet A square sandbox has an area of 16 square feet. If you wanted to double the area, what size should you make the sides of the new sandbox? 16 2
