Thank you!! <3
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
