Answer:
π
Step-by-step explanation:
Ratio obtained by dividing the perimeter of a circle by its diameter is defined by π ( a mathematical constant).
If it is approximated up to 2 decimal digit, it is represented by 3.14, because of this March 14th is celebrated as π day.
If we want to approximate π up to 3 decimal digits, we can remember this fraction 355/113( very easy to remember it is 113355-the first half in the denominator and the second half in the numerator).
π is a non-repeating, non terminating decimal number-irrational number or it is also transcendental(it is not an algebraic root).
Internationally there are many competitions as well related to π, like memorizing the digits of π and so on.
