The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The number π appears in many formulae across mathematics and physics .
That's why we compiled this list of funny Pi memes to replace all that math confusion with some good old humor. So, happy Pi Day! Enjoy these memes (along with maybe a slice of pie or two).
Pi Day is an annual celebration of the mathematical constant π (pi). Pi Day is observed on March 14 (the 3rd month) since 3, 1, and 4 are the first three significant figures of π , and it was first celebrated in the United States.
Leibniz's formula converges extremely slowly: it exhibits sublinear convergence. Calculating π to 10 correct decimal places using direct summation of the series requires precisely five billion terms because 4 2 k + 1 < 10−10 for k > 2 × 1010 − 1 2 (one needs to apply Calabrese error bound ).
i 2 = − 1 {\displaystyle i^ {2}=-1} , and. π {\displaystyle \pi } is pi, the ratio of the circumference of a circle to its diameter. Euler's identity is named after the Swiss mathematician Leonhard Euler. It is a special case of Euler's formula when evaluated for .

A History of Pi (also titled A History of π) is a 1970 non-fiction book by Petr Beckmann that presents a layman's introduction to the concept of the mathematical constant pi (π).
The table below is a brief chronology of computed numerical values of, or bounds on, the mathematical constant pi (π). For more detailed explanations for some of these calculations, see Approximations of π. As of March 2024, π has been calculated to 105 trillion decimal digits.
