Step-by-step explanation:
In the given figure , radius of the circle : r= 10 u
Central angle made by Arc ED: = 90° ( right angle )
Now , the area of the segment is given by :-
Area of segment = Area of sector (ECD) - Area of triangle(ECD) (i)
Formula : Area of right triangle = 0.5 x Base x Height
Area of sector =
Using above formulas in (i) and substituting corresponding values , we get
Area of segment =
Hence, the correct answer is A 28.50 sq. u
