What is an annulus?

An annulus (the Latin word for "little ring" is anulus / annulus, with plural anuli / annuli) is a ring-shaped object, a region bounded by two concentric circles; equivalently, it is the set difference between two concentric disks. The adjectival form is annular (as in annular eclipse). The open annulus is topologically equivalent to both the open cylinder S × (0,1) and the punctured plane.

How to Calculate Area of a Sector of an Annulus?

Area of a Sector of an Annulus calculator uses Area=((pi*Angle A)/360)*(Radius 1^2-Radius 2^2) to calculate the Area, The Area of a Sector of an Annulus formula is defined as A=(pi.B/360)(R^2-r^2) where R is radius of outer circle and r is radius of inner circle. Area and is denoted by A symbol.

How to calculate Area of a Sector of an Annulus using this online calculator? To use this online calculator for Area of a Sector of an Annulus, enter Angle A (∠A), Radius 1 (r1) and Radius 2 (r2) and hit the calculate button. Here is how the Area of a Sector of an Annulus calculation can be explained with given input values -> -12.566371 = ((pi*30)/360)*(11^2-13^2).

FAQ

What is Area of a Sector of an Annulus?
The Area of a Sector of an Annulus formula is defined as A=(pi.B/360)(R^2-r^2) where R is radius of outer circle and r is radius of inner circle and is represented as A=((pi*∠A)/360)*(r1^2-r2^2) or Area=((pi*Angle A)/360)*(Radius 1^2-Radius 2^2). The angle A is one of the angles of a triangle, Radius 1 is a radial line from the focus to any point of a curve and Radius 2 is a radial line from the focus to any point of a curve.
How to calculate Area of a Sector of an Annulus?
The Area of a Sector of an Annulus formula is defined as A=(pi.B/360)(R^2-r^2) where R is radius of outer circle and r is radius of inner circle is calculated using Area=((pi*Angle A)/360)*(Radius 1^2-Radius 2^2). To calculate Area of a Sector of an Annulus, you need Angle A (∠A), Radius 1 (r1) and Radius 2 (r2). With our tool, you need to enter the respective value for Angle A, Radius 1 and Radius 2 and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
