The length of the hour hand of a clock is 6cm.find the area of sector

1.	The length of the hour hand of a clock is 6cm.find the area of sector swept by this hour hand in90 minutes
Answer» ANSWER: $Area of sector = \frac{ θ}{360} πr2$ $\frac{90}{360} \times \frac{22}{7} \times 6 \times 6 \\ = > \frac{1}{4} \times \frac{22}{7} \times 6 \times 6 \\ = > 28.28sq.units$

The length of the hour hand of a clock is 6cm.find the area of sector swept by this hour hand in90 minutes

Answer»

$Area of sector = \frac{ θ}{360} πr2$

$\frac{90}{360} \times \frac{22}{7} \times 6 \times 6 \\ = > \frac{1}{4} \times \frac{22}{7} \times 6 \times 6 \\ = > 28.28sq.units$
