Question

Can you answer this

Answer 1

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