Formulas For Pi
Main formula to find value of Pi is taking the ratio of the circumference of the circle and the diameter of the circle.
π = Circumference / Diameter = 3.14159… = 22/7

Pi Formulas
Pi formulas are used to calculate the value of Pi(π). If the circumference and diameter of a circle are known, we can use them to compute the value of Pi(π). Pi is a Greek letter whose sign is π, and it is the ratio of the circumference of any circle to its diameter in geometry.
