pie r formula is 22/7 when we divide 22/7 it will be 3.14 and 3.14 is an irrational number and irrational number can not be formula of any sum then how the pie formula is 22/7.explain it with reason.

22/7 is not pi

Step-by-step explanation:

22/7 is just a close approximation for pi, not pi itself.

If you put 22/7 into a calculator, you get:

3.142857...

While the number pi itself is:

3.1415926...

You can notice that pi is actually different than 22/7, even though the two numbers start out the same and are close to each other. Frequently in geometry, you use 22/7 as pi because it's so close and makes calculation easier.

Hope this helps!
