Determine arc length from chord

WebThe arc length is the measure of the distance along the curved line making up the arc.It is longer than the straight line distance between its endpoints (which would be a chord) There is a shorthand way of writing the length of an arc: This is read as "The length of the arc AB is 10". The lower case L in the front is short for 'length'. WebThe radius is: R=h2+c28h{\displaystyle R={\tfrac {h}{2}}+{\tfrac {c^{2}}{8h}}}[1] The central angle is. θ=2arcsin⁡c2R{\displaystyle \theta =2\arcsin {\tfrac {c}{2R}}} Chord …
