Calculating the volume of a cylinder

I have a cylinder. The diamter is 8 and the heigh is 12in.

So its v-3.14r^2h

So 3.14(4^2)(12)
(3.14)(16)(12)
and I keep getting 602.88 which is wrong please explain what im doing wrong!!!
The choices are
1.256pi in^3
2. 224pi in^3
3.192pi in^3
4. 768pi in^3

Perhaps you did not measure it correctly.

anonymous · Answer

Oh, you need to not multiply pi into it.

anonymous · Answer

Why dont i mulitply pi into it?

anonymous · Answer

it's just  (16)(12)

anonymous · Answer

192pi in^3 = 192(3.14) in^3

anonymous · Answer

Because clearly they didn't multiply pi into it.

anonymous · Answer

They left it unmultiplied.... just tacked it on to the side.

oh ok. Thank you for correcting me
