Tennis ball with a diameter of 2.5 inches are sold in cans of three the can is a cylinder what is the volume of the space not occupied by the tennis balls? Assume the tennis balls touch the can on the sides top and bottom round to the nearest tenth

First we need to find the volume of the three tennis balls:

V = 4/3 x Pi x r^3

V = 4/3 x Pi x 1.25^3

V = 8.18

Since there are three tennis balls:

8.18 x 3 = 24.54

Then we need to solve for the cylinder:

V = Pi x r^2 x h

V = Pi x 1.25^2 x (2.5 x 3)

V = 36.81

Then we need to find the total amount of space between the tennis balls and the cylinder

38.81 - 24.54 = 12.27 inches

12.27 inches to the nearest tenth is 12.30 inches
