Answer 1

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.
