In the given figure, O is the centre of the circle with AC = 24 cm, AB = 7 cm and △ BOD = 90∘. Find the area of shaded region.
[Use π = 3.14]
In right triangle ABC
Now,∠COD+∠BOD=180o ( Linear pair angles )
Now, the area of the shaded region = Area of the sector having the central angle 360o–90o – Area of triangle ABC
Hence, the area of the shaded region is 283.97 cm2
