Calculator Inputs and Outputs
Inputs
- Radius — example: 10
- Central angle (°) — example: 90
Results
- Centroid distance from center
- Sector area
- Arc length
Formula used
For a circular sector, centroid distance from the center is 4R sin(θ/2)/(3θ), with θ in radians.
How to Use the Circular Sector Centroid Calculator

Understanding the Results
The primary answer appears first. Supporting outputs show related quantities, conversions, dates, costs, ratios, or intermediate values. Calculations keep additional precision before display rounding.
Accuracy Tips
- Use measured values and consistent units.
- Review assumptions, rates, timing, and efficiency inputs.
- Recalculate after changing any condition.
