Circular Sector, Arc Length & Central Angle Diagrams
True-scale circular sector diagrams with shaded sector area, central angle α, arc length, and optional dashed full reference circle.
Key formulas & geometric relations
A_sett = π · r² · α / 360° · l_arco = 2 · π · r · α / 360° · 2p = 2 · r + l_arco
