Using the volume of a sphere, the total volume of air inside six of Jake's basketballs is of 2140.8 cubic inches.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given as follows:

V = \frac{4\pi r^3}{3}

From the problem, since the properly inflated basketball measures 8.8 inches across, the diameter is of 8.8 inches, hence the radius is:

r = 8.8/2 = 4.4 inches.

Then the volume in cubic inches of a single ball is:

V = 4 x pi x (4.4)³/3 = 2140.8 cubic inches.

For the six balls:

6 x 356.8 = 2140.8 cubic inches.

Then subtract 132 from 220

220 - 132 = 88
