A largest sphere is to be carved out of a right circular cylinder of radius 7 cm and height 14 cm. Find the volume of the sphere. (Answer correct to the nearest integer).
Radius of cylinder =7cm
Height of cylinder =14cm
•Volume of sphere = volume of cylinder
= π×r2×h
= 227×7×7×14
= ×22×7×14
= 2156cm2
• Volume of sphere =2156cm2
