Area of shaded region = Area (sector OAPB) - Area (Triangle OAB)
Area of sector = [tex] \frac{C}{360} \pi r^{2} [/tex] = 24.504 sq.cm
Area of triangle = [tex] \frac{ab sin(C)}{2} [/tex] = 17.61 sq.cm

Area of shaded region = 24.504 - 17.61 = 6.894 ≈ 6.89 sq.cm

//r = radius;   C = angle between radii / Sides;   a,b = sides of the triangle
