Best ResponseYou've already chosen the best response.0that means that we want r by itself. So everything on the right hand side must go away except the r

Best ResponseYou've already chosen the best response.0\[V=\frac{1}{3}\pi r^2h\] What do you want to get rid of first?

Best ResponseYou've already chosen the best response.0great that's division. Opposite of division is multiplication so we have to multiply both sides by 3\[3*V=3*\frac{1}{3}πr^2h\]\[3*V=πr^2h\]

Best ResponseYou've already chosen the best response.0now we must get rid of pi and h so we have to divide both sides by pi and h....what do you get then?

Best ResponseYou've already chosen the best response.0great now we need to square root both sides.

Best ResponseYou've already chosen the best response.0ok square root takes away the squared part in r^2 watch \[\frac{3V}{\pi h}=r^2\]\[\sqrt{\frac{3V}{\pi h}}= \sqrt{r^2}\]\[\sqrt{\frac{3V}{\pi h}}= r\]

Best ResponseYou've already chosen the best response.0but wait we square root both sides so we need the plus or minus\[\pm \sqrt{\frac{3V}{\pi h}} =r\]
