Question

In a clock the long hand is of 8cm and the short hand is of 7cm. if the clock runs for 4 days find out the total distance covered by both the hands?

Answer 1

Hour hand makes a full rotation in 12 hours.One full rotation in 12 hours =>2πr=14π cm traversed every 12 hours.For one day(24 hours ), we have 28π cm, twice that of a 12 hour period.For 3 days, we then have 4 x 28 π=112π cm traversed.Long Hand ( Minute hand)One full rotation in 1 hour =>2πr=16π cm traversed every hour.For one day, we have 24 x  16 π=384π cm.For 4 days, we then have 4 x 384π=1536π cm traversed.Total DistanceFor the total, we have 112π+1536π=1648π cm.

Answer 2

Answer:

1648

Step-by-step explanation:

One full rotation in 12 hours =>2πr=14π cm traversed every 12 hours. For one day(24 hours ), we have 28π cm, twice that of a 12 hour period. For 3 days, we then have 4 x 28 π=112π cm traversed. Long Hand ( Minute hand)One full rotation in 1 hour =>2πr=16π cm traversed every hour.
