Answer 2

Answer:

$65.94 cm^2$

Step-by-step explanation:

Time = 11:20 am to  11:55am = 35 minutes

60 minutes = 360°

So, 1 minute = $\frac{360}{60}$

So, 1 minute =6°

So, 35 minutes = $6 \times 35=210^{\circ}$

The hour hand of a clock is 6cm long .

Area swept by hour hand = $\frac{\theta}{360} \pi r^2$

                                         = $\frac{210}{360} 3.14 \times 6^2$

                                         = $65.94$

Hence the area swept by hour hand is  $65.94 cm^2$
