A rubber ball is in the shape of a sphere and has a radius of 6 inches. The center of the ball is a hollow sphere that has a radius of 4 inches as shown. What is the volume, in cubic inches, of the hollow center of the ball? Please use 3.14 for π

Answer 1

Radius of the hollow centre of ball = 4 in
Volume = 4/3 πr³ = 4/3 * 3.14* 4³ = 267.95 in³

Volume of hollow centre is 267.95 in³
