So from the known arc length and radius (or diameter), you can find the angle. WebArc measure is only dependent on the measure of the central angle that intercepts that arc. So your maximum arc measure is going to be 360 degrees. Your minimum arc measure is going to be zero degrees. It's measured in degrees, not in units of length that arc length would be measured in. So, let me write this down. fishing flea market rolling meadows
