Answer 1

Answer:

Step-by-step 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:

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

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

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

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.
