So remember that the equation for the volume of a cone is [tex] V=\pi r^2\frac{h}{3} [/tex] and the volume of a cylinder is [tex] V=\pi r^2h [/tex] . All we have to do to get to the volume of the cylinder from the volume of the cone is multiply the cone volume by 3. [tex] 36\pi *3=108\pi [/tex]
In short, your answer is going to be 108π in^3, or the last option.
