Nine subtracted from negative seven would be sixteen.
To solve for r, you just need to isolate r. To do that, divide by h and π on both sides:

Then, square root both sides to get rid of the 'squared':

Or, if you wanted the answer in terms of π, then just don't divide by it, just divide by h and then square root it.
