Question 144690
The volume of a right circular cone is exactly 1/3 of the volume of the right circular cylinder with the same base radius and height.  The volume of the cylinder is the area of the base times the height.  The area of the base is the area of a circle with the given radius, namely {{{pi*r^2}}}.  That makes the volume of the cylinder {{{pi*r^2h}}}, and the volume of the cone: {{{(pi*r^2h)/3}}}.  Plug in the numbers, do the arithmetic, and round to the nearest cc.
