Question

how much distance does the tip of a minute hand of length 8.4 cm over in a day.​

Answer 1

Answer:

22

Step-by-step explanation:

In one day the minute hand covers 24 rounds while the hour hand covers 2 rounds

Let radius of circular path covered by minute hand : R = 14 cm

and radius of circular path covered by hour hand : r = 7 cm

Total distance travelled = 24×2πR+2×2πr

= 48πR+4πr

= 4π(12×14+7)cm

= 4×

7

22

×175 cm

= 2200 cm = 22 m
