Question

Medal and Fan. Find the missing measure for a right circular cone given the following information.

Find V if r = 2 and L.A. = 12pi.

Answer 1

Answer choices:\[A=(16/3)\sqrt{2\pi}\]\[B=16\sqrt{2\pi}\]\[C=4\sqrt{38\pi}\]

Answer 2

Answer 3

The height is the square root of 32

Answer 4

my bad ... i mentiond for cylinder. ...

Answer 5

so for cone ...u got the la and r
\[2\pi \sqrt{h^2 + 4} = 12\]

Answer 6

get h from above equation...and volume = \[\frac{ \pi r^2h }{ 3 }\]

Answer 7

it 12 *pi

Answer 8

Did I get h right? If not, how do I solve for h underneath the square root sign?

Answer 9

\[\sqrt32 = 4\sqrt2\]

Answer 10

@4everaddicted2anime there ???
and the first option is it
\[\frac{ 16 }{ 3 }\sqrt{2} ~\pi ~~or~~\frac{ 16 }{ 3 }\sqrt{2\pi}\]

Answer 11

Thank you
