Where did the math symbol pi in math come from?

'pi' is the lower case letter 'p' from the Classical Greek Alphabet. It refers to 'proportion, because for all circles, however, large of small , the constant of proportion (p/pi) between the circumference and the diameter is 3.141592.... , which is an irrational number, which means it cannot be converted to a ratio/fraction. Casually, the decimals recur to infinity and there is no regular order in the decimal digits. Algebraically, Circumference is directly proportional to diameter. Reduced to letters C is directly proportional to d. This is then equated with a constant(k) C = k*d k = C/d From ancient times the 'k' was substituted by 'pi/p' as it refers to 'proportion'. Hence we have pi = C/d or C = pi*d 'd' being the length of two(2) radii is substitutied again as C = 2pir In school/college, when learning about circle geometry, you will probably be given pi = 3.14, 3.1416 or 22/7 . These figures are only APPROXIMATIONS, but are given for ease of learning.
