Perimeter of Circle is 2πr , But Why? (International Pi day special )

2πr - This formula was the first time ,I learnt the existence of the constant 'pi' in school.

Brings many middle school memories back - us still figuring out how the apple pie is different from this pi (Imagine our confusion on pi day) while going crazy over the idea of becoming teenager (well, that was a major dissapointment tho😂)

We just accepted the fact back then and moved on, never questioned it since.

Well, this writer did.

After intensive research, integration and alot of coffee, this is the proof I landed on:-

Tada!

We just proved one of the most fundamental equations of Maths and Physics!

14th March -- 14/3

Pi Day is observed on March 14 (3/14 in the month/day format) since 3, 1, and 4 are the first three significant figures of π.

< Quick fact :- Its also happens to be the birthday of the genius scientist (and international tongue model) - Einstein >

I wish y'all
