The formula for calculating the volume of a cone is solve this formula for h

Answer:
[tex]V = \frac{1}{3} \pi {r}^{2} h \\ [/tex]
multiply either sides by 3:
[tex]3 \times V = ( \frac{1}{3} \pi {r}^{2} h) \times 3 \\ \\ 3V = \pi {r}^{2} h[/tex]
divide either sides by πr² :
[tex]{ \boxed{ \boxed{h = \frac{3V}{\pi {r}^{2} } }}} \\ [/tex]
