**Pi is one of the most extremely useful and fundamental quantities we know of. It is defined as the ratio of a circle's circumference to its diameter **

The application of Pi in real life include several areas like Geometry, Science, Trigonometry and Nature, etc.

Formulae from other branches of science also include π in some of their important formulae, including sciences such as statistics, fractals, thermodynamics, mechanics, cosmology, number theory, and electromagnetism.

It's also used to measure how fast and how powerful a computer is; because they can use it to check its accuracy and if there is any problems in its software or hardware.

It is also used to get the value of trigonometry function like sine, cosine, tangent...etc. It can measure circular velocity of things like truck wheel, motor shafts, engine parts, gears, and it also measures of Ac voltage across a coil and a capacitor in fact they have a filter with a special name to it because it does not like high frequency but let the low frequency in ;you guess it the Pi filter .

Using pi, it can measure things like ocean wave, light waves, sound waves, river bends, radioactive particle distribution and probability like the distribution of pennies, the grid of nails and mountains by using a series of circles.
