Question

If a tennis ball has a diameter of 14, find the volume of the tennis ball.

  1. 345.8
  2. 523.6
  3. 1436
  4. 205.1

hintHint:

The tennis ball is a sphere.
The volume of a sphere is given by 4 over 3 cross times straight pi cross times left parenthesis radius right parenthesis cubed

The correct answer is: 1436


    Volume equals 4 over 3 πr cubed
    equals 4 over 3 cross times straight pi cross times 7 cubed
equals 1436 space inches cubed
