'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.

What does the pi symbol stand for in math?
Pi is usually used as 3.14 in math because it originally goes on to infinity. Therefore, using two significant digits (the most popular used significant digit out there), Pi is abreviated to 3.14. The original Pi goes on forever, but is something like this: 3.147938401643257580923756348170125346938463728395647399047683 583057202350254183503827502854030284820472927492947291248...

How does an artist use pi?
Ok an artist uses pi to describe math in a drawing. That's it, just math in a drawing, only another way than goin into details when it all adds up to he same thing so pi for an artist is making a symbol of math in his/her drawing. Thank You!
