So, we know the snow plow tire turned or went around 29 times, namely 29 revolutions, and recall that one revolution is a 2π angle in radians.
since the tire went around 29 times, so it made an angle of 29 * 2π, or 58π.
we know the street is 116 meters long, namely "an arc made by that 58π angle is 116".
