So my school is weird, and instead of using 3.14 for math equations as to equate for pi, they use just 3.

I was wondering if anyone could help me with this question.
Find the volume of this cone, use 3 for pi [dialogue atop the question]
6 inches circumference, 3 inches radius. 11 inches in height.
I do not need the entire formula to solve it, but it would appreciated.

I have no clue myself why they do this. It is so stupid.

This is messed up in so many ways!

Since C = 2πr, if it has a 6" circumference and a 3" radius, then it appears that π=1

in any case, the volume is V = 1/3 πr^2 h
so plug in your numbers and let 'er rip.
