find the surace area of the cylinder in terms of pi

A cylinder is shown. Its radius is labeled 6 inches and its height is labeled 12 inches.

1 answer

The formula for the surface area of a cylinder is:

SA = 2πr² + 2πrh

where r is the radius and h is the height. Plugging in the given values, we get:

SA = 2π(6²) + 2π(6)(12)
SA = 72π + 144π
SA = 216π

Therefore, the surface area of the cylinder in terms of pi is 216π square inches.
