Problem
Which of the following equations is equivalent to $S=\pi r^{2} h$ ? $h=S-\pi r^{2}$ $h=\frac{S}{\pi r^{2}}$ $h=\frac{\pi r^{2}}{S}$ $h=S+\pi r^{2}$
Solution
Step 1 ：Isolate h in the given equation $S=\pi r^{2} h$: $h=\frac{S}{\pi r^{2}}$
Step 2 ：Final Answer: \(\boxed{h=\frac{S}{\pi r^{2}}}\)
