Answer 1

Answer:

D

Step-by-step explanation:

Volume of a cylinder is equal to the area of the base circle times the height of the cylinder.

The area of your base circle is $\pi r^2$ where r=15 and they are using $\pi$ as 3.14.

So we have the area of your base circle is $3.14 \cdot 15^2=706.5$ inches squared.

Now to find the volume of a cylinder again you just multiply your base area by your cylinder and you get:

$40 \cot 706.5=28260$ cubic inches
