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.
22cm^{2} 
B.
44cm^{2} 
C.
66cm^{2} 
D.
88cm^{2}
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})
