The minute hand of a clock is 10 inches long. How many inches long, to the nearest tenth of an inch, is the arc the minute hand sweeps through between 3:30 p.m. and 4:06 p.m.?
---------------
The arc is 360/60 = 6 degrees/minute
330 to 406 is 36 minutes
Arc = 216 degs
Length = 2*pi*r*216/360 = 2*pi*10*(3/5) = 12pi inches
