Hi,
I cannot figure out this question, please help.

Semi-trailer trucks have an odometer 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 1.20 m diameter and goes through 300,000 rotations, how many kilometers should the odometer read? (Enter a number.) 100 1 x km
