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

You know how math is reversible? Like, not only does 2 × 2 = 4, but also 4 ÷ 2 = 2?

How π is found is just reversing the numbers in a similar way. You can measure the radius of a circle. You can measure the circumference. If you have those two values, you can calculate π. Other constants are discovered in similar ways.
