How to Calculate Central Angle of Annulus Sector given Diagonal?
Central Angle of Annulus Sector given Diagonal calculator uses Central Angle of Annulus Sector = acos((Outer Circle Radius of Annulus^2+Inner Circle Radius of Annulus^2-Diagonal of Annulus Sector^2)/(2*Outer Circle Radius of Annulus*Inner Circle Radius of Annulus)) to calculate the Central Angle of Annulus Sector, The Central Angle of Annulus Sector given Diagonal formula is defined as the angle whose apex (vertex) is the center of the concentric circles of Annulus and whose legs (sides) are radii intersecting the circles in four distinct points, calculated using diagonal of Annulus Sector. Central Angle of Annulus Sector is denoted by ∠_{Central(Sector)} symbol.
How to calculate Central Angle of Annulus Sector given Diagonal using this online calculator? To use this online calculator for Central Angle of Annulus Sector given Diagonal, enter Outer Circle Radius of Annulus (r_{Outer}), Inner Circle Radius of Annulus (r_{Inner}) & Diagonal of Annulus Sector (d_{Sector}) and hit the calculate button. Here is how the Central Angle of Annulus Sector given Diagonal calculation can be explained with given input values -> 43.53115 = acos((10^2+6^2-7^2)/(2*10*6)).
