Question

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

Answer 1

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

`\text{ Volume of 1 basketball \lparen sphere\rparen =}(4)/(3)\pi r^3`
`Volume\text{ of 1 ball}=(4)/(3)\text{ x }\pi\text{ 4.4}^3\text{ = 113.58}\pi\text{ inches}^3`

`Volume\text{ of 6 balls = 6 x 113.56}\pi\text{ = 681.36}\pi\text{ inches}^3`

The answer is option A
