C/d as constant

  1. Lets say that "d" is diametr of a circly,and C is the perimetr(length).
    Why C/d = pi (3.14) is a constant?? I know the proof of archimides with poligons,from which found the value of pi,but how we know that C/d is always equal with a constant that we named as π=3.14;

    Thanks !!!

  3. I found it guys. The proof use similar triangles etc....
    Thanks for your time !!!
  4. This also requires assumptions of Euclidean geometry. In spherical geometry it is not constant.
