The volume of any pyramidal solid is (height/3)*base area. The curved surface area of a cone is given by π*r*s, where s is the length of the sloping edge (found by Pythagoras' theorem).

notes
This calc gives the surface areas of the flat and curved surfaces separately, for convenience.
The center of mass of a cone is 1/4 of the way towards the peak from the center of the base.
