Please answer i need help

Answer 1

`452.16 inches^3`

Explanation:

Well first we have to use the formula
`\pi r^2h` where for pi we will be repacking it with 3.14.

So the radius is 4 inches and the height is 9 inches.

So we have to plug them in
`(3.14)(4)^2(9)`.

So using PEMDAS we have to so
`4^2` first.

So
`4^2` is 16 and now we have to multiply it by 9 and 3.14 and we get 452.16in^3.
