You can put this solution on YOUR website!
h, length of cone
r, radius of bottom or base
pi for abourt 3.14

2pi%2Ar=17pi
r=%2817pi%29%2F%282pi%29
highlight_green%28r=17%2F2%29

h=-5%2B2r
h=2r-5
h=2%2817%2F2%29-5
h=17-5
highlight_green%28h=12%29

You have two quantities now known, and the question is, find the volume of the cone. Volume %281%2F3%29h%2Api%2Ar%5E2.
