# Circle segment area

A segment of a circle is the part of a circle that is bounded by an arc of a circle and its chord. Our online calculator calculates the area, arc length, chord length, height and perimeter of a circle segment. There are several options for calculating the segment parameters – by angle, by chord, by radius, by height and length of the arc..

**Segment area by radius and angle**
