Transcript and Presenter's Notes

Learn to find the surface area of prisms and

cylinders.

Vocabulary

surface area lateral face lateral surface

Surface area is the sum of the areas of all

surfaces of a figure. The lateral faces of a

prism are parallelograms that connect the bases.

The lateral surface of a cylinder is the curved

surface.

Additional Example 2 Exploring the Effects of

Changing Dimensions

A cylinder has diameter 8 in. and height 3 in.

Explain whether tripling the height would have

the same effect on the surface area as tripling

the radius.

They would not have the same effect. Tripling the

radius would increase the surface area more than

tripling the height.

Try This Example 2

A cylinder has diameter 6 in. and height 2 in.

Explain whether doubling the height would have

the same effect on the surface area as doubling

the radius.

Additional Example 3 Application

A cylindrical soup can is 7.6 cm in diameter and

11.2 cm tall. What is the area of the label that

covers the side of the can?

Only the lateral surface needs to be covered.

Try This Example 3

A cylindrical storage tank that is 6 ft in

diameter and 12 ft tall needs to be painted. The

paint will cover 100 square feet per gallon. How

many gallons will it take to paint the tank?
