Answer:

$\sqrt{\frac{3V}{\pi h} }$

Step-by-step explanation:

We have $V = \frac{1}{3} \pi r^2h$ .

We can multiply both sides by 3 to get:

$3V = \pi r^2h$

Divide by $\pi$ by both sides

$\frac{3V}{\pi} = r^2h$

And divide by h by both sides:

$\frac{3V}{\pi h} = r^2$

And finally take the square root of both sides.

$\sqrt{\frac{3V}{\pi h} } = r$

Done!
