Question

Find the volume and round to the nearest tenth as needed

Answer 1

Answer: 1962.4 cubic mm

Explanation:

The volume of the larger cone is
`V=(1)/(3)(\pi)(10^(2))(20)=(2000\pi)/(3)`

The volume of the smaller cone is
`V=(1)/(3)(\pi)(3^(2))(14)=42\pi`.

So, the volume is
`(2000\pi)/(3)-42\pi \approx \boxed{1962.4}`
