While many theorize that the concept of pi has existed since the Ancient Egyptian Empire, the first 'modern' mathematician to calculate pi with any large degree of accuracy (and record his work) was Archimedes of Ancient Greece.

Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
His major praise is from his three universal laws of gravity.

diameter = circumference / pi diameter = radius * 2
The first person to calculate pi was Archimedes, around 250 B.C. Using the formula:A = pi r^2
Pi = circumference/diameter
No. Pi is a finite number.
Euclid
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Area = pi * r2 Circumference = 2 * pi * r Pi = 3.141592 r = square root of Area/pi Cir then = 2 * pi * (square root of Area/pi)
Pythagoras was credited with discovering the relationship of a radius with a circumference. Hence the term Pi (Pye).
