Answer:

b. 340 in.

Explanation:

The area of a cylinder is
$\pi$ *
r^(2) *h, so you can substitute the values you have in.

You would get
$\pi$ * 3 * 3 * 12 = 108 *
$\pi$

Since you are estimating, use 3.14 for pi.

Then, you do 108 * 3.14 and you get 339.12, which is closest to answer choice b, 340 inches.
