An arc of a circle subtends an angle 70o at the centre. If the radius of the circle is 6cm, calculate the area of the sector subtended by the given angle.((pi) = (frac{22}{7}))

  • A.
    22cm2
  • B.
    44cm2
  • C.
    66cm2
  • D.
    88cm2
Correct Answer: Option A
Explanation

Area of a sector = (frac{theta}{360°} times pi r^{2})

r = 6cm; (theta) = 70°.

Area of the sector = (frac{70}{360} times frac{22}{7} times 6^{2})

= (22 cm^{2})
