The minute hand of a clock is 6 inches long. What distance does its tip move in 16 minutes?
the radian angle for 16 minutes
= (16/60)(2π) = 8π/15 radians
arclength = rØ
= 6(8π/15) = 16π/5 inches or 10.053 inches
one circumference = 2π(6) = 12π
so the fraction of rotation = 16/60
distance covered = (16/60)(12π = 16π/5
