Question

11. The length of the hour hand of a clock is 4.9 cm. Find the distance travelled by the tip of the hour hand in a week ​

Answer 1

Answer:

length of hour hand = 4.9 cm

⇒ Distance travelled by tip in one hour = circumference of circle

⇒ Distance travelled by tip in one day (24 hours) = 24 × 75.46 cm² = 1811.04 cm²

⇒ Distance travelled by tip in one week (7 days) = 7 × 1811.04 cm² = 12677.28 cm²
