Prove A = πr^2 using Integral Calculus - Area of the Circle Proof

In this video, I will show you how to prove that the area of a circle is A = p*r^2 (pi r squared where r is the radius) using integral calculus. This is an important topic for students in high school or in calculus as the exam may require you to write the proof for the area of the circle formula.
