Radical form

V = pi *r^2 * h divide by pi * h

V / (pi * h) = r^2 take the square root of both sides

√ [ V / (pi * h) ] = r

Exponential form

[ V / (pi * h) ] ^ (1/2) = r

4356 pi = pi * r^2 * 9 divide both sides by 9pi

(4356 pi ) / ( 9 pi) = r^2

484 = r^2 take the square root of both sides

22 cm = r
