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 <span>≈ 6.89 sq.cm

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

Sum = n + n+1 + n+2 + n+3 + n+4 = 5n + 10 = 5(n + 2)

So the sum is always divisible by 5, for any value of n
