The capacity of a cylinder varies jointly with its height and the square of its radius. If a cylinder with a radius of 3 centimeters and a height of 6 centimeters has a capacity of 169.56 cubic centimeters, what will the capacity be of a cylinder with radius 6 centimeters and height 7 centimeters?

Solution

r = 6 cm

h = 7 cm

Capacity = pi * r² * h

               = 3.14 * 6² * 7

                = 791.28 cubic centemeters (ans)
