Tanks A and B are each in the shape of a right circular cylinder. The interior of tank A has a height of 10 meters and a circumference of 12 meters, and the interior of tank B has a height of 12 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 answers:
A) 80%
B) 90%
C) 100%
D) 110%
E) 120%
The radius of tank A is 12/(2*pi).   The capacity of tank A is 10*pi*144 / (4*pi^2) = 360 / (pi)   The radius of tank B is 10 / (2*pi).   The capacity of tank B is 12*pi*100 / (4*pi^2) = 300 / (pi)   Tank A / Tank B = 360/300 = 12/10 = 120%   The answer is 120%.
