Solution
The correct option is A269.5cm2 Radius of the circle with center at A =AT=14cm Radius of the circle with center at B =AT−AB=(14−3.5)cm=10.5cm Area of the circle with center A =π(14)2 =616cm2 Area of the circle with center B =π(10.5)2 =346.5cm2 Thus, area of the shaded region =(616−346.5)cm2 =269.5cm2
