Answer 1

Answer:

$452.16 inches^3$

Step-by-step 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.
