Question

Chris knows that the formula for finding the volume of a cone is:

V = 13πr2h
Use the formula for the volume of a cone to find the formula for the height of a cone.
A h = V/3πr(squared)
B h = 3V/πr(squared)
C h = 3V/πr
D A h = V3πr(squared)

Answer 1

actually its V= 1/3pi(r)2h

Explanation:

Answer 2

It is given in the question that the formula of volume of cone is

`V = (1)/(3) \pi r^2 h`

Where V is the volume, r is the radius and h is the height.

And we have to find an expression for h.

First we multiply both sides by 3, and on doing that we will get

`3 V= \pi r^2h`

Now to isolate h, we have to get rid of pi r square by dividing.

`h= (3V)/( \pi r^2)`

Therefore the correct option is B.
