V= pie r^2h r=4.38m V= 368m^3 h=?
So you know what the value for pi is, value for r is, and the value for V. So the only part is looking for h.
You can achieve that by just manipulating the equation: V=pi(r^2)(h) into h=...
V/ pi = r^2*h
V/(pi*r^2) = h
Then when you get the equation for h, you can plug in and solve.
