To find the length of the arc of a semicircle, use the formula ( L = \pi r ), where ( r ) is the radius of the semicircle. Since a semicircle is half of a full circle, the total circumference of a circle is ( 2\pi r ), and the length of the arc for the semicircle is half of that. Simply multiply the radius by ( \pi ) to get the arc length.
