THE INTRODUCTION OF THE SYMBOL π IN 1706 Since antiquity, the calculation of the value of π has been a challenge for people from many parts of the world. The constant π is defined as the ratio of the circumference or periphery, π ριφ´ ρ ια in Greek, p of a circle to its diameter d π = p/d
Introductions to Pi. Introduction to the classical constants. General. Golden ratio. The division of a line segment whose total length is a + b into two parts a and b where the ratio of a + b to a is equal to the ratio a to b is known as the golden ratio.

Formulas for π. Stephen Lucas. Department of Mathematics and Statistics. James Madison University, Harrisonburg VA. π = 3.14159.
There are many formulas of pi of many types. Among others, these include series, products, geometric constructions, limits, special values, and pi iterations. pi is intimately related to the properties of circles and spheres. For a circle of radius r, the circumference and area are given by C = 2pir (1) A = pir^2.
