Pi (π) is the ratio of a circle’s circumference to its diameter. By measuring circular objects, it has always turned out that a circle is a little more than 3 times its width around.  The mathematician Archimedes used polygons with many sides to approximate circles and determined that Pi was approximately 22/7.

William Jones first used the symbol for Pi, the Greek symbol “π”, in 1706.  In recent years, Pi has been calculated to over one trillion digits beyond its decimal.
