22/ 7 is not equal to pi

we know that pi is irrational and cannot be expressed as a ratio

for many practical purposes , we need some approximate value of pi

we found that 22/7 is really good approximation for practical purposes particularly when we do manual calculation

pi = 3.1415.....

22/7 = 3.1428....

actually 22/7 is > pi
