Find arc length given chord length
WebApr 9, 2024 · There are two important formulas to find the length of the chords. The formula for the length of a chord is given as: Chord Length Formula Using Perpendicular Distance from the Center Chord Length = \ [2 \times \sqrt {r^2 - d^2} \] Chord Length Formula Using Trigonometry Chord Length =\ [ 2 \times r \times sin (\frac {c} {2}) \] WebThe length of the chord can be found using the following formula: chord (a) = 2r × sin ( θ 2) Thus, the length of the chord a is equal to 2 times the radius r times the sine of the central angle θ divided by 2. How to Find Sector Area The area of a sector can be found using the formula: sector area (A) = r² × θ 2
