Question

in the given figure O is the centre of the circle with ac is equals to 24 cm and a b is equals to 7 cm and angle b o d is equal to 90 degree find the area of the shaded region

Answer 1

Find the area of the circle then subtract the area of a quarter circle and the area of the triangle.
Diameter = √24^2+7^2= 25
hence Area of circle= 625π/4

Area of quarter circle =625π/16
Area of triangle = 12×7= 84

Now the final answer will be = 625π/4-625π/16-84=284.15 square units
