The fornula V=2(3.14)r^2 h is used to find the volume of a cylinder. Solve this formula for r^2 and h.

V = 2 * π * r^2 * h

r^2 = V ÷ 2 * π * h

h = V ÷ 2 * π * r^2

V  =  2(3.14)r^2h

 

Soving for r^2  

V = 6.28 r^2 h     divide both sides by   6.28h

V / [ 6.28h]  = r^2

 

Solving for h

v = 6.28r^2h     divide both sides by 6.28r^2

V / [ 6.28r^2 ]  =  h
