M.KathleenThe mathematical pi comes back into the historical picture, due in part by William Jones who introduced the use of the Greek symbol for pi in 1706. The use of this symbol was popularized by Swiss mathematician Leonhard Euler in 1737. Meanwhile, during the slave trade, the sweet potato pie was invented..

What does the pi symbol mean?
Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.
Why is pi 22 divided 7? Value of Pi (π) in Fractions
It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22/7 is used for everyday calculations.
Where did Pi Day originated?
The idea of “Pi Day” originated with physicist Larry Shaw, who organized the first Pi Day celebration at the San Francisco Exploratorium in 1988. Almost exactly twenty-one years later, on March 11, 2009, the U.S. House of Representatives passed a resolution proclaiming March 14 to be National Pi Day.
What does 3.14 mean?

Will pi ever end?
The Answer: Pi is an irrational number. As such, it has no final digit. Furthermore, there is no pattern to its digits.
Why is pi and 22 7 different?
Since both 22 and 7 are integers 22/7 is rational. Just to be clear, pi is an irrational number, so it has a non terminating non repeating decimal expansion.

Is pi bigger than infinity? Pi is finite, whereas its expression is infinite. Pi has a finite value between 3 and 4, precisely, more than 3.1, then 3.15 and so on. Hence, pi is a real number, but since it is irrational, its decimal representation is endless, so we call it infinite.
