In a circle with centre O and radius 'r ', another smaller circle is inscribed with centre D and radius half that of the bigger circle as shown in the figure. Tangents to the smaller circle from a point A(A-O-T) on the bigger circle meet at E and F and meet its diameter when produced at B and C. Then, Ar`DeltaABC` is :
