Webpi, in mathematics, the ratio of the circumference of a circle to its diameter. The symbol π was devised by British mathematician William Jones in 1706 to represent the ratio and was later popularized by Swiss mathematician Leonhard Euler. Because pi is irrational (not equal to the ratio of any two whole numbers), its digits do not repeat, and an approximation … WebThe ratio of the circumference to the diameter of a circle can never be determined precisely! Mathematicians use a symbol, the Greek letter π π (pi), to refer to it. That is …
