  1. 1 What exactly is pi?

    Pi is written as the Greek word for p, or π which is the ratio of the circumference to the diameter of that particular circle. The ratio will always equal pi, regardless of the circle size. The value of pi is circa 3.14 in decimal form. However, pi is an irrational number, that implies its decimal form neither ends nor becomes repetitive.

    Let's demonstrate you by representing different numbers of digits past the decimal:

    • pi to 10 digits- 3.14
    • pi to 100 digits

    And, so on...

  2. 2 Significance of pi

    pi seems a simple enough concept as it helps in defining the ratio of the circumference of the circle to its diameter. As it turns out to be an irrational number, which makes its precise value is inherently unknowable. However, pi's equity goes beyond math.

    Pi day is celebrated on March 14 every year because of its approximate value (3.14 implying 3/14).

  3. 3 Other information about pi

    It is mostly used in some computations regarding circles. Only circumference and diameter are related to pi. Astonishingly, it also connects the radius or diameter of the circle by the formulae mentioned below-
    Area= (pi) x (radius squared)

    Many times pi is unexpectedly observed being used in an array of mathematical solutions. For instance, the sum of infinite series.

    Furthermore, the significance of pi has been recognized for more than 4000 years. With the advancement of technology and the emergence of computers, we are informed about more than first six billion digits of pi.
