The relationship of arcs is:
  S '/ S = ((11/6) * pi * 6) / (2 * pi * 6)
  Rewriting we have:
  S '/ S = ((11/6)) / (2)
  S '/ S = 11/12
  Therefore, the area of the shaded region is:
  A '= (S' / S) * A
  Where A: area of the complete circle:
  A '= (11/12) * pi * 6^2
  A '= (11/12) * pi * 36
  A '= (11) * pi * 3
  A '= (33) * pi 
  Answer:
 
 The area of the shaded region is:
