Question

14. The length of the minute hand of a clock is 14 cm, then the area swept by the
minute hand in 10 min- is
1) 100 cm
2) 102.66 cm
3) 106.7 cm
4) 98.7 cm​

Answer 1

Answer:

The minute hand of a clock sweeps 360∘ in 60 minutes. Hence the minute hand will sweep an area equal to the area of a sector of radius 14 cm and angle 90∘. Here θ=90∘ and r =14cm.

Answer 2

Answer:

We have the area swept by the minute hand of the clock in 60 minutes =πr2=227(14)2=616 square centimetres. Hence the area swept by the minute hand clock in 1 min =61660 square centimetres.
