so \[12 \pi = \pi r \sqrt{h^2 + r^2}\]and\[V=\frac{ 1 }{ 3 }\pi r^2 h\]right?
yes
and r = 2?
yea
so you can solve the first equation for h, correct? then you can use that value of h with r = 2 in the second equation to solve for the volume...

but you need the slant height as well to solve this
the slant height is \(\sqrt{h^2+r^2}\) where h is the vertical height and r is the radius.
oh okay i get it now thanks :)
