You can put this solution on YOUR website!
V = (1/3) (3.142) r^2 h
Multiply both sides by 3 to get:
(3.142)r^2h = 3V
Divide both sides by 3.142h to get:
r^2 = (3V)/(3.124h)
Take the square root of both sides to get:
r = sqrt[(3V)/(3.124h)]

How do I get this formula to read with the r on the left hand side reading r = ???????
V = 1/3 3.142 r2 h
:
This looks like the volume of a cone which is:
V = 1%2F3%29* pi%2Ar%5E2%2Ah
:
Multiply equation by 3:
3V = pi%2Ar%5E2%2Ah
:
Divide both sides by pi%2Ah
%283V%29%2F%28pi%2Ah%29 = r^2
:
r = sqrt%28%283V%29%2F%28pi%2Ah%29%29
:
Is this what you had in mind?
