What is π (pi)?

π is a mathematical constant that appears in many formulas across mathematics and physics. Pi is an irrational number that can’t be expressed as the ratio of two integers, like ⅖ or ¾.

However, 22/7 is the fraction commonly used to approximate π.

Interestingly, the decimal representation of π neither ends nor follows any repeating pattern. And, that’s why π is called a transcendental number.

Wikipedia defines π as a mathematical constant that is the ratio of a circle’s circumference to its diameter, approximately equal to 3.14159…
