Since they want the answer in meters, not cm, first convert the 6 cm length of the second hand to meters:
6 cm = (6 cm)*(0.01 m/cm) = 0.06 m
The tip of the second hand travels in a circle of radius 0.06 m. The distance it travels in one circle around (one minute) is:
Distance Traveled in One Minute = 2·pi·r = (2)(3.14)(0.06) = 0.377 m
One circle around is 60 seconds or one minute. The number of minutes in a day (24 hours) is:
Number of Minutes in a Day = (60 min/hour)(24 hours) = 1440 min
There are 1440 minutes in a day, so the second hand makes 1440 complete revolutions (circles) in one day. The total distance that the tip of the second hand will travel is:
Total Distance = (Distance traveled in One Minute)·(Number of Minutes in a Day)
Can you finish it from here? Remember to round to the nearest meter.
