Question

compare py and 22/7​

Answer 1

Step-by-step explanation:

π is a constant for every circle.

If we divide any circle with its diameter we will get this number: ( 3.14159265..... )

Notice: this number π is irrational as it has non terminating and non repeating decimal.

doing calculation with 3.14159265....... is very difficult and not logical also.

therefore we use:

22/7 = 3.14285714 (approx 3.14)

note 3.14285714 is not equal to 3.14159265

so, 22/7 is a good approximation of π in order to make calculation easier.
