Question

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

Answer 1

Answer:

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

Step-by-step explanation:

Answer 2

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

$V = \frac{1}{3} \pi r^2 h$

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.

$h= \frac{3V}{ \pi r^2}$

Therefore the correct option is B.
