Pi is a Greek letter. Why it was made could be asked of every other character in every language: to help communicate a spoken sound or letter on paper in a uniformly recognisable way. Its use to represent the "circle constant" (the area, circumference and volumes of circles, cones, cylinders and spheres can be calculated from at most two linear measurements) is probably just chance.
A pi equals 3.1415326535897932384626433832795028841971693993751058209749445923
The pI of Isoleucine is 5.98
Pi is infinite and has no end.
Pi is caused by the ratio of a circle's circumference to its diameter.
no every periodic number is rational but pi is irrational
pi = circumference/diameter
Nobody made pi. Pi is the ratio of the circumference of a circle to its diameter and that is universal. Pi would have been pi even if there were never any humans.
Archimedes made pi more precise
Larry Shaw made pi day on 3, 14, 1989.
Nobody made the number pi. It existed before mankind, before the sun and the solar system.
Being optimistic and real in his agenda made Pi's resilience so successful.
pi was not made - it is not a human artefact. The ratio of the circumference of a circle to its diameter exists independent of human existence.
it was made in 2000 BC
