Answer:
Area of a circle is pi *

then multiply that by the height
Explanation:
diameter = 10
radius is diameter / 2
r = 10/2 = 5
A = pi *

A = 78.5398
height * A = volume
12 * 78.5398 = 942.477
So about 942 , answer 3 looks right :) sorry I got to your question late, send me a note , when you have a question, so I'll see :)
