How can a black hole's density be infinite?

They always talk about the diameter of the event horizon and how it varies by mass and that they can infer the mass. So a x million sun solar mass black hole might have a diameter of 1 AU

Could you not figure out how much mass is in that area? It's a finite amount of mass in a measurable area, has can it be infinitely dense? How can black holes of different stellar masses have the same density?
