I think you add the exponents im not sure haven't done it in long time
A circle is 360° , if youdivide<span> an arc's </span>degree measure<span> by 360°, you find the fraction of the circle's </span>circumference<span> that the arc</span>makes<span> up. Then, if you multiply the length all the way around the circle </span>by that fraction, you get the length along the arc.
