Circle constant (π)

The circle constant π = 3.1415… describes the ratio between the circumference and the diameter of a circle

π =   circumference 



One quintillion figures after decimal point were already computed, and there never develops a pattern that is repeated. Mathematicians proved that this will never happen, and therefore call it a transcendental number.

It is an important number, and plays a role in many calculations that deal with circles, waves and movements.


Example 1

A calculation with the number π gives

π + π = 2π



In 1882, the German mathematician Ferdinand von Lindemann proved that pi is a transcendental number.
