Hey everyone! :) 


I'm really struggling with this question and I'd really appreciate some help. I've provided a screenshot for the question.

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

 

 

 

cool cool cool
