Dear Prasanth,The equation of the circle is x2 + y2 = r2 .Here (x,y) is the coordinate on circle and r is the radius of the circle.

the center radius form of the  equation is the fomate (x-h)2+(y-k)2=r2,with the center being at the point (h,k)and the radius being “r” this form of equation is helpful, since you easily find the center and the radius.
