Question

Find the surface area of the cylinder. Round your answer to the nearest tenth.

Answer 1

90pi

Explanation:

area of a circle = Pi R^2 = Pi 3^2, area is = to 9pi for one base. Multiply that by 2 since there are two bases, so now u have 18pi. To find the long side, you need to find the circumference which is 2PiR, giving you 6pi*12 = 72pi+18pi = 90pi, which is the answer.
