A sector of a circle of radius 7cm has an area of 44cm2. Calculate the angle of the sector correct to the nearest degree [Take π = 22/7]
  • A.
    6o
  • B.
    26o
  • C.
    52o
  • D.
    103o
  • E.
    206o
Correct Answer: Option D
Explanation

πr2 = 360o

44cm2 = θ; ∴ θ =

44/πr2

x 360o = 102.9o = 103o
