WebThe solution is simple, if you consider that the perimeter of the shaded region is simply the sum of the arc length and the chord length. The arc length = Total Perimeter * (74/360) = 2*pi*8*74/360 = 10.332 m. The chord length = 2*r*sin (Angle/360) = 16*sin (74*pi/360) The sum of these two lengths is the perimeter of the shaded area.
