Apr 25, 2023 · Arc length is the distance between one endpoint of an arc on a circle to the other. In this article, we’ll tell you what formulas you need and how to use them to find a circle's arc length. Read on to learn more!
- To find the arc length, set up the formula Arc length = 2 x pi x radius x (arc's central angle/360), where the arc's central angle is measured in d...
- If you're not given the central angle, you'll typically be given the sector area of the arc. To find the arc length with a sector area, multiply th...
- That is correct. The vertex of an inscribed angle is on the outside of a circle. When an inscribed angle and a central angle share the same arc on...
Arc lengths are denoted by s, since the Latin word for length (or size) is spatium . In the following lines, represents the radius of a circle, is its diameter, is its circumference, is the length of an arc of the circle, and is the angle which the arc subtends at the centre of the circle.
