$Cone properties diagram$

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).

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.
