Formula
Use c = 2√(r²−d²). r na radius and d na perpendicular distance from centre to chord for di same unit. Chord length c dey use dat length unit.
Find chord length from radius and perpendicular distance to the centre.
Example wey show the calculation
- Di radius (m)
- 5
- Distance from centre to chord (m)
- 3
- Length of di chord
- 8 m
- Di smaller centre angle
- 106.260204708 °
Where e fit work and limits
Use consistent units. Result follow the assumptions wey you enter.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
