Why is Pi 22 divided 7?

The pi value in fraction is 22 / 7. It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22 / 7 is used for everyday calculations. ‘ π ‘ is not equal to the ratio of any two number, which makes it an irrational number.

What is pi used for today?

In basic mathematics, pi is used to find the area and circumference of a circle. Pi is used to find area by multiplying the radius squared times pi. So, in trying to find the area of a circle with a radius of 3 centimeters, π32 = 28.27 cm.
