(#M40002101) CSC QUESTION Keep an EYE

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?

Solution

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 = 0.8
so capacity of A will be 80% of the capacity of B
