Exercise 1 Page 622

Use the formula for the surface area of a cylinder.

603.2 yd^2

Practice makes perfect

We are given a cylinder and want to find its surface area.

To calculate the surface area of a cylinder, we can use the following formula. S=2π rh+2π r^2 In this formula, r is the radius of the base and h is the height of the cylinder. By substituting r with 6 and h with 10 into the formula, we can solve for S. Let's do it!

S=2π rh+2π r^2

SubstituteII

r= 6, h= 10

S=2π( 6)( 10)+2π( 6)^2
