WebArc length is a fraction of circumference. Area of a sector is a fractions of the area of a circle. Both can be calculated using the angle at the centre and the diameter or radius. WebIf you know the arc length and the radius, then the angle that is subtended by the sector is θ = L / r where L= arc length and r = radius (Angle in radians, of course.) Thus, the area of …
WebA sector is the area of a circle which has been enclosed by two radii and the arc between them. A sector is not to be confused with a segment of a circle. A segment is when the area enclosed by the chord of a circle and the arc of the chord.
