Question

What is the exact volume of the cone?

base 7in
height 4in

PLEASE HELP ASAP

Answer 1

The volume formula of a cone is
`(1)/(3) \pi r^(2) h` the r is the radius and h is the height. However, if you multiply by pi, you will get an approximated volume of the cone. So we will multiply like this for now.
`(1)/(3) r^(2) h` Don't worry, we'll use pi in the end.

I'm going to assume that 7 inches is your radius. We need to plug in 7 for r and 4 in for h into the equation. Once we do that, it will look like this.
`(1)/(3) 7^(2) 4`


`(1)/(3)` means we will need to divide one by 3. That gives us 0.33333... now we have to multiply by
`7^(2)` we get 16.33333... now the last thing we need to do is multiply by 4, which is h. We get 65.33333. Add pi and you have your answer.
`65.333333333 \pi`
