Tanks A and B are each in the shape of a right circular cylinder. The interior of tank A has a height of 9 meters and a circumference of 8 meters, and the interior of tank B has a height of 8 meters and a circumference of 10 meters. The capacity of tank A is what percent of the capacity of tank B?	Choose the correct choice from the following choices:
A) 72%  B) 80%  C) 100%  D) 120%  E) 125%
For A, r=8/2pi. Its capacity = (4pi)^2 * 9= 144pi   For B, r=10/pi. Its capacity = (5pi)^2 *8 = 200pi   72%/B = 144pi/200pi = 0.72   72%144  /200=
