Why does Pi equal 3.14(…)?

Question

I’m seeking a physical science based explanation of why Pi equals what it does in our universe, not necessarily a mathematical answer.

What laws govern such constants…curvature of the universe? In our expanding universe, will this constant ever change?

Answer 1

Pi equals what it does because we use a base-10 numbering system, and so the ratio of a circle’s circumference to its diameter comes out to be 3.1415927 etc.

In other bases, the number is obviously different, but it all boils down to the ratio of a circle.
