Question

Recall, π is defined as the ratio of the circumference (say c) of a circle to its diameter (say d,) That is,π= c/d .this seems to contradiet the fact that π is irrational .how you resolve this Contracdiction ?​

Answer 1

There is no contradiction. When we measure a value with a scale, we only obtain an approximate value. We never obtain an exact value. Therefore, we may not realize whether c or d is irrational. The value of π is almost equal to 22/7 or 3.142857…
