Circle Chord Length from Angle

Circle Chord Length from Angle helps with geometry and applied mathematics. Use Circle radius metres, Central angle degrees to estimate m rather than relying on a fixed rule of thumb. This calculator uses the relationship 2*radius*sin(pi*angle/360). Returns nonnegative chord length for the full-circle central angle range. It runs locally in your browser, so the values can be changed to explore a different scenario without transmitting the entered numbers to an external calculation service.

How to use this calculator

  1. Check the measurements for Circle radius metres, Central angle degrees. Each field displays its input unit; do not mix cm, m, seconds or minutes.
  2. Enter the quantities for your own geometry and applied mathematics scenario. Use ungrouped numeric values, with a period for decimals.
  3. Read the result in m and compare the underlying formula with your real situation. Returns nonnegative chord length for the full-circle central angle range.

How the Circle Chord Length from Angle works

Result in m = 2*radius*sin(pi*angle/360). Inputs are expressed in the units shown in their labels.

  • The output uses the current values of Circle radius metres, Central angle degrees, with no live service data, manufacturer information or personal information. This is a model, not a real-time measurement.
  • The tool rejects blank, nonnumeric and out-of-range inputs instead of displaying a misleading result. Returns nonnegative chord length for the full-circle central angle range. Review quantities, precision and units before using the result for a purchase, plan or technical choice.

Worked examples

Worked example: Circle Chord Length from Angle

Suppose Circle radius metres = 4, Central angle degrees = 65. The calculator processes these numeric quantities using its defined relationship.

Apply 2*radius*sin(pi*angle/360) to those inputs, preserving the unit conversions in the expression.

Calculated value: approximately 4.298397 m.

Understanding the result

The default example gives approximately 4.298397 m; this is a mathematical output based on the example inputs, not a forecast of actual observed conditions.

Returns nonnegative chord length for the full-circle central angle range.

Important notes
