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?
multiply(multiply(power(divide(8, 10), const_2), divide(9, 8)), const_100)
"for a , r = 8 / 2 pi . its capacity = ( 4 pi ) ^ 2 * 9 = 144 pi for b , r = 10 / pi . its capacity = ( 5 pi ) ^ 2 * 8 = 200 pi a / b = 144 pi / 200 pi = 0.72 a"
