Question 178384: S=2pierh+2piersqured
solve for h
Answer by ilana(307)   (Show Source):
You can put this solution on YOUR website! I think the letter you want is "pi", not "pie". I will write "pi" as "p" just to make it easier to read/write. So the equation is S=2prh+2pr^2, and we need to solve for h. Since h is in one term of the equation, put all other terms on their own side. So subtract 2pr^2 from each side. So S-2pr^2=2prh. Now the right side of the equation has h times 2pr. So divide each side by 2pr. So h=(S-2pr^2)/2pr.
