How To Find The Arc Length Of A Circle Using The Formula Youtube Learn how to find the arc length of a circle using the formula, the angle of a sector, or the radius of a circle. watch this video and solve problems with arc lengths. Arc measure definition. an arc is a segment of a circle around the circumference. an arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. this angle measure can be in radians or degrees, and we can easily convert between each with the formula π \pi π radians = 180°. In this lesson we’ll look at arcs of circles and how to find their measure. an arc is part of the circumference of a circle. there are three types of arcs: 1) minor arcs are less than 180º, 2) major arcs are more than 180º, and 3) semi circular arcs are exactly 180º. In other words, the central angle of a minor arc measures less than a semicircle. in the given circle, ab is the minor arc. in contrast, a major arc is an arc that subtends an angle of more than 180° to the center of the circle. thus, the central angle of a major arc measures more than a semicircle. in the given circle acb is the major arc.
