Definition In Euclidean plane geometry n is defined as the ratio of a circumference to its diameter: / The ratio c/d is constant,regardless of a circle’s size. For example if a circle has twice the diameter d of another circle it will also have twice the circumference C, preserving the ratio c/d.

These definition depend on result of Euclidean geometry, such as the fact that all circle are similar. This can be considered a problem when n occur in areas or mathematics that otherwise do not involve geometry. For this reason, mathematicians often prefer to define n without reference to geometry, instead selecting one of its analytic properties asa definition. A common choice is to define n as twice the smallest positive

x for which cos(x)=0. The formulas below illustrate other (equivalent) definitions.

history the ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi=3. One Babylonian table (ca. 1990-1680 BC) indicates a value of 3125 f
