Answer 3

what is the formula for volume of a cone?

Answer 4

Volume of a cone is pi*r^2*(h/3)

Answer 5

v=1/3 pi x r^2xh

Answer 6

\[V=\pi r^2\frac{ h }{ 3 }\]

Answer 7

good so now what is our r and h?

Answer 8

So let's plug in everything we have.
r=12
h=8

\[V=\pi (12)^2 \frac{ 8 }{ 3 }\]

Can you figure this out?

Answer 9

so its 144x8/3 right??
