the area of a circle with radius r, A = Ï r^2.
Pronounced as Pi R square

A=Ïr²
or
The area of a circle equals the product of the irrational constant, pi, and the square of the radius measure of the circle.

the area is the radius timed 2. exsample if you want to bye a pool and they say its a 12 foot radius then the area is 24. times by 2. 12x2=24 you got it now?

good question for area of circle first take length and then breadth of circle,then multiply both of these and then take square root of the no. obtained,then multiply some arbitary constant 'x' and then 'y' and then take double integral from limits 0 to infinity and then after you obtain the answer get up and go to the roof and suicide ,hope i get your news on tv
