Introductory Algebra for College Students (7th Edition)

$$h = \frac{V}{\pi r^{2}}$$ The original equation is the formula to find the volume of a cylinder.
We want to solve this equation for $h$, so we need to isolate $h$. Divide both sides by $\pi r^{2}$: $$h = \frac{V}{\pi r^{2}}$$ The original equation is the formula to find the volume of a cylinder.
