I'm trying to figure out the distance traveled in a circular motion. This is for a traffic court case, I need to figure out how far my car traveled in an intersection. So far, I've only been able to find equations for determining speed. I have speed. I have time. I also have the radius of the circular movement (I measured the intersection and made an average to determine the curve because the turn was not a perfect circle). What I need is distance. What would be the equation to determine the distance traveled?
