How to Calculate Central Angle of Annulus Sector given Perimeter and Outer Circle Radius?
Central Angle of Annulus Sector given Perimeter and Outer Circle Radius calculator uses Central Angle of Annulus Sector = (Perimeter of Annulus Sector-(2*Breadth of Annulus))/((2*Outer Circle Radius of Annulus)-Breadth of Annulus) to calculate the Central Angle of Annulus Sector, The Central Angle of Annulus Sector given Perimeter and Outer Circle Radius 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 perimeter, outer circle radius and breadth of Annulus Sector. Central Angle of Annulus Sector is denoted by ∠_{Central(Sector)} symbol.
How to calculate Central Angle of Annulus Sector given Perimeter and Outer Circle Radius using this online calculator? To use this online calculator for Central Angle of Annulus Sector given Perimeter and Outer Circle Radius, enter Perimeter of Annulus Sector (P_{Sector}), Breadth of Annulus (b) & Outer Circle Radius of Annulus (r_{Outer}) and hit the calculate button. Here is how the Central Angle of Annulus Sector given Perimeter and Outer Circle Radius calculation can be explained with given input values -> 42.97183 = (20-(2*4))/((2*10)-4).
