Answer:
90pi
Step-by-step 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.
