WebArea of a sector = (θr2)/2 Where θ = the measure of the central angle given in radians. Area of a sector given the arc length Given the length of the arc, the area of a sector is given by, Area of a sector = rL/2 Where r = radius of the circle. L = arc length. Let’s work out a couple of example problems involving the area of a sector. Example 1 Web18 May 2024 · 1 degree corresponds to an arc length 2π R /360. To find the arc length for an angle θ, multiply the result above by θ: 1 x θ = θ corresponds to an arc length (2πR/360) x θ. So arc length s for an angle θ is: s = (2π R /360) x θ = π Rθ /180. The derivation is much simpler for radians:
