In a circle the length of an arc is given by

WebThe length of an arc is just a fraction of the circumference of the circle of the same radius. The circumference is given by 2πr, where r is the radius. For example, an arc that is halfway round a circle is half the circumference of a circle. An arc that is a quarter way round a circle is quarter the circumference of a circle. WebJan 11, 2024 · The length of an arc is found by forming a ratio of the arc to the whole circle, then multiplying it by the formula for circumference, either 2\pi r 2πr or \pi d πd, like this: Arc lengt {h}_ {\overset\frown {AB}}=\left (\frac {m\overset\frown {AB}} {360°}\right)\left (2\pi r\right) ArclengthAB⌢ = ( 360°mAB⌢)(2πr) Or, if you have the diameter:
