Quantitative Aptitude (CDS) Coordinate Geometry

Two circles, each of radius r, with centres P and Q, are such that each circle passes through the centre of the other circle. Then the area common to

the circles is less than one-third of the sum of the areas of the two circles by

$\frac{\sqrt{3}r^{2}}{4}$

$\frac{\sqrt{3}r^{2}}{3}$

$\frac{\sqrt{3}r^{2}}{2}$

$\sqrt{3}r^{2}$

Area of common circle.< 2 × Area of equilateral triangle APQ
