Question

IF THE LENGTH OF THE HAND OF A WRIST WATCH IS 1.4 cm find the distance travelled by the tip of the minute hand in the day​

Answer 1

Answer:

the minute hand will complete 24 revolutions in 24 hrs.

so

no of revolutions in 1 hr = 1 revolution.

distance travelled in 1 revolution = 2πr = 2*(22/7)*1.4 = 8.8 cm

so distance traveled in 24 hrs = 8.8†24= 211.2
