Question

A sphere is just enclosed inside a right circular cylinder. If volume of the gap between

cylinder and sphere is 90 cm3, find volume of the sphere.​

Answer 1

Since the sphere is enclosed inside the Cylinder

Thus

Heigth of cylinder = Diameter of sphere

Thus

H = 2r

Volume of Cylinder = Pi * R ^2 * H

             Pi * R ^2 * H = 240 m^3

             Pi * R^2 * 2r = 240

                   

Thus Volume of sphere = 4/3 pi r^3

Putting the values we get the answer
