Understanding Circular Segments

A circular segment is the portion of a circle enclosed by a chord and an arc. The area of a segment depends on both the radius of the circle and the central angle that subtends the arc.

Formula

Area = (r² / 2) × (θ - sin(θ)) where: r = radius θ = central angle in radians
