The outer radius of a hollow metallic spherical ball is 15 cm while the thickness of the metal used to make it is 12 cm. Find volume of the metal used in making this ball.
Inner radius of the ball = 15 - 12 = 3 cm Required volume = 4/3 × π × (153 - 33) = 4/3 × π × (3375 - 27) = 4/3 × π × 3348 = 4464π
