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 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 answers:
A) 90%
B) 50%
C) 60%
D) 70%
E) 80%
circumference of A = 2(pie)r = 8 so r = 4/pie   volume = pie(4/pie)^2*10 = 160/pie   circumference of B = 2(pie)r = 10 so r = 5/pie   volume = pie(5/pie)^2*8 = 200/pie   so ratio of capacities = 160/200=

<output>4/5 = around 0.8</output>
0.8   so capacity of A will be 80% of the capacity of B   ANSW80%R:80%
