Human: Hi, my homework requires me to find the volume of a sphere. Can you explain how to do that?

Assistant: It depends on what sort of sphere we’re talking about.  There are several definitions for a sphere, but probably what you want is something called the “geometric” definition of a sphere.  There are a few ways to do this, but one way is to imagine that the sphere has been flattened out on a piece of paper.  The area of the paper is defined by a formula called “Pi”, which is approximately 3.1416...  if the radius of the sphere is “R”, the area of the circle would be approximately Pi*R2, and the “volume” would be the area multiplied by the height.  But usually the sphere is not “flattened out” in our imagination, and you need to estimate how the volume of a sphere changes when it’s not flattened out.

Assistant: I’m happy to, but I’m not sure what a “sphere” is. Is that an abstract mathematical entity, or does it have a physical existence?
