In the diagram above, O is the center of the circle of radius 3.5cm, ∠POQ = 60°. What is the area of the minor sector POQ?
[Take π = 22/7].
1481/2cm2
77cm2
321/12cm2
65/12cm2
15/6cm2
Correct answer is D
Area of sector = \frac{\theta}{360°} \times \pi r^2
= \frac{60}{360} \times \frac{22}{7} \times 3.5 \times 3.5
= \frac{77}{12}
= 6\frac{5}{12} cm^2
