Step-by-step explanation:
Radius of circle = 18.6 cm
Area of sector =
Area of sector =
Area of sector =
Area of triangle =
a = OA = radius = 18.6 cm
b = OB = radius = 18.6 cm
x =123 °
Substitute the values in the formula
Area of triangle =
Area of triangle =
So, Area of shaded region = Area of sector - Area of triangle
=
=
Hence the area of the shaded region is 226.084 sq.m.
