Formula for an arc
WebArc is a part of the circumference of a circle. If the length is zero, it will be merely a point on the boundary of the circle. And if it is of length, it will be the circumference of the circle i.e. an arc of length 2πR. Length of the … WebIn other words, when you find the arc length, given the central angle, you are finding the fractional part of the whole circle circumference based on the whole 360 degree circle: length of arc/length of circumference = central …
