What is the total volume of air inside six of hairs basketballs ?

Solution:
The shape of a basketball is a sphere.
Given that a basketball measures 8.8inches across. This means the diameter= 8.8 inches
radius = 8.8/2 = 4.4 inches
[tex]\text{ Volume of 1 basketball \lparen sphere\rparen =}\frac{4}{3}\pi r^3[/tex][tex]Volume\text{ of 1 ball}=\frac{4}{3}\text{ x }\pi\text{ 4.4}^3\text{ = 113.58}\pi\text{ inches}^3[/tex][tex]Volume\text{ of 6 balls = 6 x 113.56}\pi\text{ = 681.36}\pi\text{ inches}^3[/tex]The answer is option A
