The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
The symbol means that the ratio of the left-hand side and the right-hand side tends to one as . The symbol ≃ {\displaystyle \simeq } means that the difference between the left-hand side and the right-hand side tends to zero as n → ∞ {\displaystyle n\to \infty } .
The word is a play on the word "pi" itself and of the linguistic field of philology. There are many ways to memorize π, including the use of piems (a portmanteau, formed by combining pi and poem), which are poems that represent π in a way such that the length of each word (in letters) represents a digit.

The circumference of a circle with diameter 1 is π.. A mathematical constant is a number whose value is fixed by an unambiguous definition, often referred to by a special symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
