Tanks A and B are each in the shape of a right circular cylinder. The interior of tank A has a height of 7 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?
Select the correct option:
A) 56% B) 80% C) 100% D) 120% E) 125%
For A, r=8/2pi. Its capacity = (4pi)^2 * 7= 112pi   For B, r=10/pi. Its capacity = (5pi)^2 *8 = 200pi   56%/B = 112pi/200pi = 0.56   56%112  /200=
