Answer: 1150 cubic inches

Step-by-step explanation:

The volume of sphere is given by :-

[tex]\text{Volume}=\frac{4}{3}\pi r^3[/tex], where r is the radius of sphere.

Given: The radius of the inflated ball = 6.5 inches.

Then, the volume of inflated ball will be :-

[tex]\text{Volume of inflated ball}=\frac{4}{3}\pi (6.5)^3\\\\\Rightarrow\text{Volume of inflated ball}=\frac{4}{3}(3.14)(274.625) \\\\\Rightarrow\text{Volume of inflated ball}=1149.76333333\approx1150\ in.^3[/tex]

Hence, air will occupy the 1150 cubic inches space contained by the inflated beach ball
