answer choices :
a. 113 in.
b. 340 in.
c. 250 in.
d. 226 in.

Answer:
b. 340 in.
Step-by-step explanation:
The area of a cylinder is [tex]\pi[/tex] * [tex]r^{2}[/tex]*h, so you can substitute the values you have in.
You would get [tex]\pi[/tex] * 3 * 3 * 12 = 108 * [tex]\pi[/tex]
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.
