    What Pi really is? Before knowing our super-hero (‘Pi’) we have to remind the definition of circle. A Circle is nothing but a two-dimensional closed loop in which the set of all the points in the 2D plane is equidistant from a reference point called ‘Centre’ [1]. So, the distance from the centre to any point on the circumference of the circle is constant and the circumference of the circle can only be changed if we change this constant distance (Radius). Figure 01: Variability of Circumference with its Radius [Made with Canva] Then it can be said that radius is the only variable of circumference of any circle in the world. From this common sense, let’s form a mathematical syntax: Circumference α Radius or, Circumference α Diameter or, Circumference = Constant × Diameter Finally, Constant  = Circumference/Diameter  =  Pi  = 3.14159……………………. (Infinity)   Now, this ratio of Circumference to Diameter is a constant and this is known as ‘Pi ’, the ir...
