    I think Bruce Banner would have been able to figure it out by now. Use, the slant height and the diameter of the cone to find out the height of the cone. Then, use this height in the volume formula to find the volume.

    x^2 + 12^2 = 15^2

    so 9 is the height. now plug that into the formula they gave you to find the volume

    \[9^2+12^2=15^2\] i think?
