Question

What is the volume of the cone with 9cm base and a 15cm height

Answer 1

317.925 cubic centimeters

Explanation:

The volume of a cone is
`V = (1)/(3) \pi r^2 h`. Here the base is 9cm which could mean the diameter. The radius would be half this and r = 4.5. The height is 15. Substitute these values and simplify the formula.

`V = (1)/(3) \pi r^2 h\\\\V = (1)/(3) \pi (4.5)^2 (15)\\\\V = (1)/(3) \pi (20.25)(15)\\\\V = (953.775)/(3)\\\\V=317.925`
