Exercise 31 Page 638

Use the formula for the surface area of a cylinder.

829.4 cm^2

Practice makes perfect

The given solid is a cylinder.

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 16 into the formula, we can calculate the value of S. Let's do it!

S=2π rh+2π r^2

SubstituteII

r= 6, h= 16

S=2π( 6)( 16)+2π( 6)^2
