If the diameter of a youth baseball is 2.8 inches and the diameter of an adult softball is 3.8 inches, what is the approximate difference in their volumes? Use 3.14 for pi . Round to the nearest tenth.

volume = 4/3 x 3.14 x r^3

4/3 * 3.14 = 4.18666

radius of youth ball = 2.8/2 = 1.4

volume = 4.18666 x 1.4^3 = 11.488 cubic inches


radius of adult ball =  3.8/2 = 1.9

 voulume = 4.18666 x 1.9^3 = 28.716

28.72 - 11.49 = 17.2 cubic inches difference

The approximate difference in their volumes is 17.2 cubic inches.

Given the information that:

  • baseball is 2.8 inches
  • adult softball is 3.8 inches
  • 3.14 for pi

The formula for the volume of a sphere is V = 4/3 πr³. See it being used in an example where we have the diameter of the sphere. This way:

  • radius of youth ball = 2.8/2 = 1.4
  • volume = 4.18666 x 1.4^3 = 11.488 cubic inches
  • radius of adult ball =  3.8/2 = 1.9
  • voulume = 4.18666 x 1.9^3 = 28.716

The difference in their volume is:
