alright so to solve for pi you must move all the other variables to the left
[tex]v = \frac{1}{3} \pi {r}^{2} h [/tex]
first divide the h as the opposite operation of multiplication is division
[tex] \frac{v}{h} = \frac{ \frac{1}{3}\pi {r}^{2}h }{h} \\ \frac{v}{h} = \frac{1}{3} \pi {r}^{2} [/tex]
now you multiply each side by 3 or 3/1 to get rid of the fraction
[tex] \frac{v}{h} \times \frac{3}{1} = \frac{1}{3} \pi {r}^{2} \times \frac{3}{1} \\ \frac{3v}{h} = \pi {r}^{2} [/tex]
now square root each side
[tex] \sqrt{ \frac{3v}{h} } = \pi[/tex]
now that is your final answer
