1. Semi-trailer trucks have an odometer (an instrument for measuring the distance traveled by a vehicle) on one hub of a trailer wheel. The hub is weighted so that it does not rotate, but it contains gears to count the number of wheel revolutions-it then calculates the distance traveled. If the wheel has a 1.40 m diameter and goes through 220000 rotations, how many kilometers should the odometer read? Hint: What is the rotational angle covered in 220000 rotations? How is this angle related to the arc- length? Enter to 3 significant figures Answer: km
