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. If I find the area with some other method, I ...

This formula makes it possible to determine pi as precisely as you like in a very simple way. You don’t have to be a master of mathematics to work out the equation. But you do need patience.

The digits of pi extend into infinity, and pi is itself an irrational number, meaning it can’t be truly represented by an integer fraction (the one we often learn in school, 22/7, is not very ...

BENGALURU: Indian Institute of Science (IISc) researchers have accidentally stumbled upon a new finding -- a new series of representing the age-old mathematical formula of pi.
