Calculation path
Radius and height derive slant height by Pythagoras; one-third base area times height gives cone volume.
Calculation path
Volume = pi r^2 h / 3; slant height = sqrt(r^2 + h^2).

Choose the maximum decimal places shown. This does not increase source accuracy.
The apex is assumed directly above the circular base center and the base is included in total surface area.
