Hey Batman xD hows Gotham today?
OpenStudy (anonymous):
Volume of a cone is just pi*r^2*h/3
OpenStudy (anonymous):
\[Vc = \pi r^2 \frac{ h }{ 3 }\]

See if you can derive it :)
OpenStudy (anonymous):
If you do try to derive it, a hint would be to think of a cylinder ;)

Do they want it with the pi in the answer? If so then you have 175 pi
