The volume of a cone is `V=(1)/(3)pir^(2)h`. Make r as the subject of the formula.

A

`r=sqrt((3V^(2))/(pih))`

B

`r=sqrt((V)/(3pih))`

C

`r=sqrt((3V)/(pih))`

D

`r=sqrt((V)/(3pih))`

Text Solution

Verified by Experts

The correct Answer is:
C
(i) apply transposition
(ii) Cross multiply and make `r^(2)` as the subject.
(iii) Apply square root on both sides.
