Circle Segment: Arc & Chord

Calculate arc length, chord, area & radius of a circle segment. Works offline.

Circle Segment Calculator solves all unknown values of a circle segment instantly. Enter any two known values — radius, central angle, chord length, arc length, height, or segment area — and get all remaining results at once.
What the app calculates:

Segment area (A)
Circle radius (R)
Central angle (α)
Chord length (c)
Arc length (L)
Height (f)

The app includes a clear visual diagram with labeled parameters so you always know exactly what you are calculating.
Basic formulas for area, perimeter, height, arc length, central angle, and center of gravity are available directly in the app — useful for students and engineers who need to verify their work.
Works fully offline — no internet connection required. All calculations are instant and available anywhere.
Whether you need to find arc length from radius and angle, calculate chord length, determine segment area, or solve for central angle — Circle Segment Calculator handles it in one tap.
