A circle is 360° all the way around; therefore, if you divide anarc's<span> degree measure by 360°, you find the fraction of the circle's circumference that the </span>arc<span> makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the</span>arc<span>.</span>
