If you have a perfect sphere sitting on a flat table, what is the surface area of the sphere that is in contact with the table?

This has been bugging me for a while because it feels like it should be infinitely small, but that doesn't make practical sense.

Mathematically speaking, a perfect sphere resting on a perfectly flat surface touches the surface at a single point.

Physically, nothing is either perfectly spherical or perfectly flat. So it's just a very tiny surface.
