Given :
- Radius of circle = 8 cm.
- ∠A = 90°.
To find :
- Calculate the area of the designed region between the two quadrants of circles of radius 8 cm each.
Solution :
The area of shaded region = 2 × Area of segment BD.
To find the area of the shaded region, first we need to find the area of quadrant ABD.
Area of quadrant ABD =
Area of ∆ABD =
Area of segment BD = Area of quadrant ABD - Area of ∆ABD.
Now, we will find the area of segment BD.
Area of the shaded region,
Area of the shaded region = 2 × 18.24
.
Area of the shaded region is 36.48 cm².
