Areas related to Circles ncert solutions Chapter 12 Exercise 12.3 Question 3
3. Find the area of the shaded region, if ABCD is a square of side 14 cm and APD and BPC are semi-circles.
Solution:
Side of square = 14 cm.
Therefore, radius of both the semi-circles =r=
cm
Area of shaded portion = Area of square – Area of two semi-circles APD and BPC.
{Area of semi-circle =
}
Area of shaded portion= side x side –
