3. Recall, \(\pi\) is defined as the ratio of the circumference (say c) of a circle to its diameter (say d).
That is, \(\pi\) = c/d. This seems to contradict the fact that \(\pi\) is irrational.
How will you resolve this contradiction?
Answer :

First of all, there is not any contradiction. \(\pi\) defined here has an approximate value of 22/7 i.e. by comparing with c/d.
Also, any value measured on scale or physically is an approx value.
