Answer» Answer: HERE IS YOUR ANSWER Step-by-step explanation: Sum of DISTANCES covered by their TIPS in one day = 1108.8 cm Step-by-step explanation: Number of rotations COMPLETED by hour HAND in 24 HOURS or in 1 day = 2 So, to find the distance traveled by hour hand, we find the circumference ⇒ Distance = no. of rotations × circumference ⇒ Distance = 2 × 2π·r ⇒ Distance = 4 × 3.14 × 4.2 = 52.8 cm Number of rotations completed by minute hand in 24 hours or in 1 day = 24 So, to find the distance traveled by minute hand, we find the circumference ⇒ Distance = no. of rotations × circumference ⇒ Distance = 24 × 2π·r ⇒ Distance = 48 × 3.14 × 7 = 1056 cm Hence, Sum of distances covered by their tips in one day = 52.8 + 1056 = 1108.8 cm |
