Finding the arc length of a circle segment
WebThe Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin (θ) 2 × r 2 … WebGiven an arc or segment with known width and height: The formula for the radius is: H 2 + W 2 8 H where: W is the length of the chord defining the base of the arc H is the height measured at the midpoint of the arc's base. Derivation See How the arc radius formula is derived . Calculator Enter any two values and press 'Calculate'.
