Why do you need help?

 

A cone is a circluar pyramid.

 

The volume of any pyramid is 1/3   the volume of the corresponding prism.

 

The volume of any prism is the are of ther base  times  by the height.

 

The area of thr circlular base is  pi*r^2

 

So now you should be able to work it out.

 

Post your working (not just answer)  and I will check if you want :)
