  ## AREA OF A SECTOR FORMULA
  
  Area of sector is the part of the circle enclosed by an arc and two radii drawn to the extremities. Area of a sector can be calculated using the radius(r) and the angle(θ) created by the two radii at the center of the circle. Area of the sector is represented in length – unit2unit2 irrespective of whether the angle given is in degrees or radians. A sector with the central angle of 180° is called a half-disk and is bounded by a diameter and a semicircle. Sectors with other central angles are sometimes given special names, these include quadrants (90°), sextants (60°) and octants (45°), which come from the sector being one 4th or 6th or 8th part of a full circle.
  
  The Area of a Sector Formula is, A = πr2r2(θ360θ360)
  Where,
  r is the radius of the circle.
  θ is the angle created by the two radii at the center of the circle.
  
  ### SOLVED EXAMPLES
  
  Question 1: Find the area of a sector of a circle whose radius is 8 cm and the angle made at the center of the circle is 45o
  Solution:
  Given,
  
  r = 8 cm
  θθ = 45o
  Area of a sector
  = πr(θ360θ360)
  = π ×× 82 ×× (4536045360) cm2
  = π ×× 64 ×× 0.125 cm2
  = 25.12 cm2
