Question

What is the exact volume of the cone? (height is 9 cm, the radius is 15 cm)

Answer 1

675pi

Explanation:

The volume of a cone is
`(h\pi r^2)/(3)`, so we can plug in the values to get 225*9/3 times pi, or 675pi.

Answer 2

`675\pi\ cm^3`

Explanation:

The volume of the cone can be calculated using the formula

`V_(cone)=(1)/(3)\pi r^2h.`

In you case,

`r=15\ cm,\ h=9\ cm,`

then the exact volume of the cone is

`V_(cone)=(1)/(3)\pi\cdot (15)^2\cdot 9=675\pi\ cm^3.`
