Pi (π) is a fundamental mathematical constant that represents the ratio of a circle’s circumference to its diameter. It was first calculated by the ancient Greek mathematician Archimedes.

Origin of the Symbol

The Greek letter π (pi) is the first letter of the Greek word perimetros, meaning “circumference.”

Discovery

Pi was first rigorously calculated by Archimedes of Syracuse, a Greek mathematician, physicist, engineer, inventor, and astronomer.

Applications

Pi is used extensively in mathematics, physics, engineering, and many other scientific fields to calculate the properties of circles, spheres, and other circular or spherical objects.

Properties
