I understand the mathematical definition of Pi, but why does it end up being used in so many formulas and applications in math, engineering, physics, etc? What does it unlock?
Edit: I understand Pi is the ratio of circumference to diameter. But why is that fact make it important and useful. For example it shows up in the equation for standard normal distribution. What does Pi have to do with a normal distribution. That’s just one example.

Pi is ratio for diameter to it radius. And it unlocks just that – understanding how to evaluate that. You would see PI everywhere where it is nessessary to work with circles or their parts. Interesting part comes from understanding that many things can be painted inside circle and thus can use some of circle related equasions. As enginiring and physics havely using trigonometry it is not surprise tha PI appears in many many formulas.
