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's revolutions it then calculates the distance traveled. If the wheel has a $1\mathrm{.}0m$ diameter and goes through $177000$ rotations, how many kilometers should the odometer read?

$km$
