Pi represents the ratio of the circumference of any circle to its diameter. The approximate value of Pi is calculated up-to two decimal points, 3.14. However, since it is an irrational number, after the decimal point, the digits go on. The value of Pi in fraction is 22/7.
The value of the Pi was first calculated by Mathematician, Archimedes of Syracuse. It was later accepted by the scientific community when Leonhard Euler used the symbol of Pi in 1737.
Pi Day is celebrated by Mathematics enthusiasts every year. Pi recital competitions, Pi Day workouts are organised to stimulate interest in learning and practising mathematics.
