###### Example1.1.26

A factory makes customized plastic balls. A ball's radius can be calculated by the formula \(r(V)=\sqrt[3]{\frac{3V}{4\pi}}\text{,}\) where \(r(V)\) stands for the ball's radius for a given volume \(V\text{.}\) A customer asks for plastic balls with a volume of \(3\) cubic feet. Find the radius of those balls. Round your answer to two decimal places.
