Sir how did you write 3.14 instead of 22/7? Is it a choice or we need to do depending on the question? Normally we use 22/7 if there isn't a specified π?

[@ayushsinghbohra1361]

If they take 22/7 question takes too Much time in solving that's why they take 3.14.

how is R inversely proportional to d^2??
is it a formula that we have to learn or can we derive it??
