Using method of integration, find the area of the region enclosed between two circles
Equations of the given circles are:
Equation (i) is a circle with centre O at the origin and radius 2. Equation (ii) is a circle with centre and radius 2.
Solving equation (i) and (ii) we have
Thus, the points of intersection of the given circles are
The required area of the enclosed region OACA1O between circles
