Question

What is the surface area of a cylinder

396 pi ft^2
180 pi ft^2
192 pi ft^2
252 pi ft^2

Answer 1

252pi ft^2

Explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2pi rh

The diameter is 12 so the radius is 12/2 = 6

= 2 pi (6)^2 +2 pi *6*15

= 72 pi + 180pi

= 252pi ft^2
