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
