Pi X r X 2
The radius of the circle is a given
2 is a given
Pi ..is infinite
Last calculation of Pi according to physicist Peter Trueb, calculated pi to 22.4 trillion digits — 22,459,157,718,361, to be exact — outpacing the previous record set in 2013 by 9 million digits.
So that's why we will never know the true area of a circle 😊
