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

If you know the “diameter” of a square (the shortest distance from one edge to the opposite edge), then the ratio of the perimeter to the diameter is 4. You could ask the same question about a hexagon, an octagon, etc. — the number approaches 3.14159…. etc as the number of sides gets big.
