Project: Milky Way Volume Estimate
Estimate the volume of the [[Milky Way]] Galaxy. Assume that the Milky Way Galaxy can be modeled by a disk with radius of 52,850 light-years and thickness of 1,000 light-years. Also assume a central bulge modeled as a sphere of radius 10,000 light-years. The disk should have a 10,000 light-year hole in it so we don't double count the volume included in the sphere.
