Answer:

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

Step-by-step explanation:

To write this equation with h isolated, we cancel everything else on the right hand side of the equals sign. This means we cancel π and r².

Since both of these are attached to h by multiplication, we divide by both to cancel. We can divide by both at the same time:

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