WebThe equation for the arc length is this: Central angle/360 = Arc length/ Circumference. Since the radius is four the circumference will be eight. The equation is 104 / 360 = s/8pi. Multiply both sides by 8 pi since we need to isolate s, and you should end up with the answer which is 104*8pi / 360 = s. Hope this helps! ( 35 votes) Show more...
