Discover how to quickly find the perimeter of a sector of a circle with our easy-to-use online calculator. Simply input the radius and central angle (in degrees or radians) to get instant results. Perfect for students, engineers, and professionals needing precise geometry calculations.
Formula:
P = 2r + L
Where:
- P = Perimeter of the Sector
- r = Radius of the Circle
- L = Arc Length
- If the central angle (θ) is in radians: L = r × θ
- If the central angle (θ) is in degrees: L = (θ / 360°) × 2πr
