Answer:

Explanation:

Let's baby-step this to make it easy, ok? Begin by getting rid of all the fractions, which means we will eliminate the 3 from the 1/3 by multiplying both sides be 3:


3V=\pi r^2 h

If we want to eventually isolate the r, we need to move the h and the pi. Do this by division, since each of these is multiplied by r-squared. Doing that gives us:


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

Lastly, to undo a square, we have to take the square root. We will do that for both sides of the equals sign:


+\sqrt{(3V)/(\pi h) }=r

The positive is out front there to indicate that we don't want the negative value since distance is a measure that will never be negative.
