Written beneath: r, equals, A over pi, square rooted. The r, and the r squared are coloured blue., To find the area of a circle, the radius is squared and multiplied by π.

Swiss researchers said on Monday they had calculated the mathematical constant pi to a new world-record level of exactitude.

If you need a radius, pi is too small by half, yet the radius is the most natural way of describing a circle. Euler's formula tells us that the complex exponential of tau is unity.
