This transcendental number is used to make circles just by having the radius. Thus, everything that uses circles depend a lot on the use of pi. Just look around you and you might find many things with a circular or spherical shape. It wouldn't be possible to design them if we didn't know pi. Just a small list of things related to circles that you might find at home: your cds, dish satellite, balls, tires, coins, the shape of the water pipes in our houe, etc.

Pi is a constant that allows you to determine the area as well as the circumference of circles ... provided you know either its diameter or its radius.
