WebSep 15, 2024 · 4.2: Arc Length. In Section 4.1 we saw that one revolution has a radian measure of 2π rad. Note that 2π is the ratio of the circumference (i.e. total arc length) C of a circle to its radius r: Clearly, that ratio is independent of r. In general, the radian measure of an angle is the ratio of the arc length cut off by the corresponding central ... WebNow, the circumference of the circle is 2 PI r, where r is the radius of the circle. So the circumference of a circle is 2 PI larger than its radius. This means that in any circle, there are 2 PI radians. Therefore 360º = 2 PI …
