Question

Prove the following formulae to the given letters:
$V=\pi r^{2}h,r$

Answer 1

$v=\pi r^{2}h$ ( Volume of a cylinder)

$\frac{v}{\pi r^2}=\frac{\pi r^2}{\pi r^2}h$ ( divide both sides by $\pi r^2$ to isolate $h$)

$\frac{v}{\pi r^2}=h$ simplify you find the height $h$ is equal to $\frac{v}{\pi r^2}$

$h=\frac{v}{\pi r^2}$
