S 3 2 1. When rectified the curve gives a straight line segment with the same length as the curves arc length. So the arc makes up 16 of the circumference of the circle.
Arc Length Formula L e n g t h th 360 2 p r The arc length formula is used to find the length of an arc of a circle.
Where th equals the measure of the central angle that intercepts the arc and r equals the length of the radius. The arc length is. This is the same as the degrees version but in the degrees case the 2p360 converts the degrees to radians. S 3 2 1.
