Pi can be calculated using a random sample of darts thrown at a square and circle target.

The area of a circle is pi times the radius squared. This is half of a circle with a radius of 1 (no units) such that it would have an area of pi/2.

Google devs have calculated pi to a record 100 trillion digits. The feat's practical benefits pale next to the promotional ones.

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

The first example of a computer being to calculate Pi was in 1949, when John von Neumann and chums used ENIAC (Electronic Numerical Integrator And Computer) to compute 2,037 digits of Pi.
