Mathematics / Circumference and Area of a Circle

Mathematics / Circumference and Area of a Circle

  • Length of the arc of a sector = Ɵ / 360 x 2 Π r = Ɵ / 360 x (Circumference of circle)
  • Perimeter of a sector = 2r + Ɵ / 360 x 2 Π r
  • Area of the sector = Ɵ / 360 x Π r2 = Ɵ / 360 x (Area of the circle)
  • Area of segment = area of the corresponding sector – area of the corresponding triangle
