Answer 1

To find the volume of a cylinder, we have to use the formula:
\[V =\pi r^2 h\]
Put in the height
\[V=\pi r^2 100\]
Radius is half of diameter. Radius is 1/2 of 12 = 6. Let's put in the radius.
\[V=\pi (6^2) (100)\]
\[V=\pi(36)(100)\]
\[V=\pi\times(3600)\]
pi equals about 3.14, so let's put that in.
\[V=3.14\times 3600\]
\[V=11304\]

Looks like B is the answer.
