since h is on the right side of the equation, to solve, we need to switch it to the left side.
πr^2h=v
Then we would divide each term by πr^2 and then simplify.
r^2h/r^2=V/πr^2
Next, I would reduce the expression by canceling the common factors.
r^2h/r^2=V/πr^2 (it stays the same because all is already canceled. :D)
The final and simplified version would be:
h=v/πr^2
