Exercise 12 Page 752

Use the formula for the surface area of a cylinder.

66π m^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. Substituting r with 3 and h with 8 into the formula, we can solve for S. Let's do it!

S=2π rh+2π r^2

r= 3, h= 8

S=2π( 3)( 8)+2π( 3)^2

▼

Simplify right-hand side

Calculate power

S=2π( 3)(8)+2π(9)

Multiply

S=48π+18π

Add terms

S=66π

The surface area of the cylinder is 66π m^2.
