\displaystyle\\Answer:\ r=\sqrt{(3V)/(\pi h) } .

Explanation:


\displaystyle\\V=(1)/(3) \pi r^2h.\\

Multiply both sides of the equation by 3:


3V=\pi r^2h.

Divide both sides of the equation by πh:


\displaystyle\\(3V)/(\pi h) =(\pi r^2h)/(\pi h) \\(3V)/(\pi h)=r^2\\ r^2=(3V)/(\pi h) .\\r*r=\sqrt(3V)/(\pi h) *\sqrt{(3V)/(\pi h) } \\r=\sqrt{(3V)/(\pi h) } .\\
