Answer 1

Answer:

65.94cm 2

Step-by-step explanation:

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

60 minutes = 360°

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

60

360

So, 1 minute =6°

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

∘

The hour hand of a clock is 6cm long .

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