How does the Circular Sector Calculator work?

Area = (θ/360°) × πr² for degrees, or (θ/2) × r² for radians Then: Arc length = (θ/360°) × 2πr for degrees, or θ × r for radians Then: Perimeter = arc length + 2 radii Then: Central angle θ related to arc and radius.

Can you give an example of how to use the Circular Sector Calculator?

Example: Input r=5cm, angle 60deg gives a result of Area 13.09.

Is the Circular Sector Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
