Question
The outer radius of a hollow metallic spherical ball is
12cm while the thickness of the metal used to make it is 8 cm. Find the volume of the metal used in making this ball.Solution
Inner radius of the ball= (12-8) =4cm Required volume= 4 π/3 (12 ³ -4³) =4 π/3(1728-64) = = 4 π/3 ×1664=2218.6π
