Question

Suppose you trying to inflate a rubber ball, and you want to know the volume of the ball. The ball has a radius of 9in. What is the volume of the ball? Round to the nearest hundredth.

Answer 1

The radius of the ball is given below as

`r=9in`

The volume of the ball will be calculated using the formula below

`V=(4)/(3)\pi r^3`

By substituting the values, we will have

`\begin{gathered} V=(4)/(3)\pi r^(3) \\ V=(4)/(3)\pi*(9)^3 \\ V=(4)/(3)*\pi*729 \\ V=972\pi \\ V=3053.63in^3 \end{gathered}`

Hence,

The final answer to the nearest hundredth

`\Rightarrow3053.63in^3`
