Homework Statement
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 1.02 m diameter and goes through 210,000 rotations, how many kilometers should the odometer read?
Homework Equations
I am not sure what I am doing incorrectly?
The Attempt at a Solution
If the formula is distance/rotation =π * diameter
Then,
Distance = π* diameter * rotations
Meaning,
π * 1.02 * 210,000 = 673,016.4m * 1 km/1000m = 673.02km after rounding?
