Segment of Circle Perimeter Calculator: Find Arc & Chord Length

Calculate Segment of Circle Perimeter

Quickly determine the perimeter of a circular segment. Our easy-to-use calculator helps you find the sum of its arc length and chord length. Ideal for students, engineers, and designers needing precise geometric measurements for circles.

Formula:

The perimeter of a circular segment (P) is the sum of its arc length (L) and chord length (c).

  • Arc Length (L): L = R × θ
  • Chord Length (c): c = 2R × sin(θ/2)
  • Perimeter (P): P = L + c = R × θ + 2R × sin(θ/2)

Where:

  • R = Radius of the circle
  • θ = Central angle of the segment (in radians)
