Formula
Convert di angle a wey you enter for degrees to θ = πa/180 radians. Use A = r²θ/2 and s = rθ. r na radius, A na sector area, and s na arc length.
Find area, arc length and boundary length for circular sector.
Example wey show the calculation
- Di radius (m)
- 3
- Angle for centre of circle (degrees)
- 60
- Area inside the sector
- 4.71238898038 m²
- Length along the arc
- 3.14159265359 m
- Length round the whole boundary
- 9.14159265359 m
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.
