ANSWER
The volume of the sphere is \(113.0in^3\).
EXPLANATION
The volume of a sphere is calculated using the formula;
\(Volume=\frac{4}{3}\pi r^3\).
We were given in the question that the radius is \(3\) inches. Therefore we substitute \(r=3\) in to the formula for finding the volume to obtain;
\(Volume=\frac{4}{3}(3.14) (3)^3\)
\(\Rightarrow Volume=\frac{4}{3}(3.14) (27)\).
\(\Rightarrow Volume=4\times (3.14) (9)\)
\(\Rightarrow Volume=113.04\)
Rounding to the nearest tenth means we should round to one decimal place. This will give us;
\(Volume=113.0in^3\)
