# Circular Segment

## Circular Segment

Portion of a circle bounded by a chord and the arc subtended by the chord.

### Formula

The area of a circular segment is given by the relationship : A = r$$^{2}$$[$$\frac{α}{2}$$ – $$\frac{1}{2}\small\sin(α)$$], where α is the measure in radians of the angle at the centre.

### Example

The shaded portion of the figure is a circular segment :
