Most of us already know that pi can be approximated by 3.14 (or 3.14159 or 22/7, etc.). What is important here is the deeper meaning, which skullpatrol has aptly explained. See his first post, above. "Something that can go with many formulas, sphere, circle, cone, etc." is not an adequate definition of pi.
