 Why is the area of circle is πr2?

-Added by Himanshi Verma Mathematics » Circle


Himanshi Verma

 The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. ... This give a geometric justification that the area of a circle really is "pi r squared".
