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

Solution:

The radius of the ball is given below as

$r=9in$

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

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

By substituting the values, we will have

$\begin{gathered} V=\frac{4}{3}\pi r^{3} \\ V=\frac{4}{3}\pi\times(9)^3 \\ V=\frac{4}{3}\times\pi\times729 \\ V=972\pi \\ V=3053.63in^3 \end{gathered}$

Hence,

The final answer to the nearest hundredth

$\Rightarrow3053.63in^3$
