class manim_mobject_annularsector_001a(Scene): 
   def construct(self):
      poly = AnnularSector(outer_radius=1.1,inner_radius=0.5
      ,arc_center=(0,-2,0),start_angle=0.25,angle=1.3208,color="#33FF33",fill_color="#FFFF00",fill_opacity=1)
      self.play(ShowCreation(poly),run_time=2)
      self.play(ShowCreation(AnnularSector(arc_center=(0,0,0),start_angle=1.5708,stroke_width=50,color="#33FF33",fill_color="#FFFF00",fill_opacity=1)),run_time=2)
