Question 9:
In the given figure, AB and CD are two diameters of a circle (with centre O) perpendicular to each other and OD is the diameter of the smaller circle. If OA = 7 cm, find the area of the shaded region. [Use π = 22/7]
Answer:
Radius (r1) of larger circle = 7 cm
Radius (r2) of smaller circle = 7/2 cm
Area of the shaded region
= Area of smaller circle + Area of semi-circle AECFB − Area of ΔABC
