Areas related to Circles ncert solutions Chapter 12 Exercise 12.3 Question 2
2. Find the area of the shaded region, if radii of the two concentric circles with center O are 7 cm and 14 cm respectively and .
Let radius of bigger circle = r1 which is equal to 14 cm.
Let radius of smaller circle = r2 which is equal to 7 cm.
Area of shaded portion = Area of sector AOC - Area of sector BOD
Area of shaded portion=
