A ball is to be made with an inner radius of 2 units and an outside radius of 3 units
Concept:
The volume of sphere = 4/3π(R3 - r3)
Calculation:
The volume of the spherical balls = Material is required to make the ball.
The material required to make the ball = 4/3π(R3 - r3)
⇒ 4/3π(33 - 23)
⇒ 4/3π(19)
⇒ 76/3π.
∴ The material required to make the ball is 76/3π.
