Question

The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?​

Answer 1

B

Explanation:

Formula for finding the volume of a cone:
`V=\pi r^(2) (h)/(3)`

From the question, we can tell that the height, h, is equal to 2d or 4r.

h = 4r.

Substitute h into the volume formula:

`V=\pi r^(2) (4r)/(3)`

Rearrange to get the final equation of:

`V=(4)/(3) \pi r^(3)`
