What is annulus?

In mathematics, an annulus (plural annuli or annuluses) is the region between two concentric circles. Informally, it is shaped like a ring or a hardware washer. The word "annulus" is borrowed from the Latin word anulus or annulus meaning 'little ring'. The adjectival form is annular (as in annular eclipse).The area of an annulus is the difference in the areas of the larger circle of radius R and the smaller one of radius r

How to Calculate Perimeter of Annulus?

Perimeter of Annulus calculator uses perimeter = 2*pi*(Radius of large circle+Radius of small circle) to calculate the Perimeter, The Perimeter of Annulus formula is defined as sum of all the outermost part of Annulus where , p=2π(R+r) , p = perimeter of Annulus , R = radius of large circle of Annulus, r = radius of small circle of Annulus. Perimeter and is denoted by P symbol.

How to calculate Perimeter of Annulus using this online calculator? To use this online calculator for Perimeter of Annulus, enter Radius of large circle (R) & Radius of small circle (r) and hit the calculate button. Here is how the Perimeter of Annulus calculation can be explained with given input values -> 43.9823 = 2*pi*(5+2).

FAQ

What is Perimeter of Annulus?
The Perimeter of Annulus formula is defined as sum of all the outermost part of Annulus where , p=2π(R+r) , p = perimeter of Annulus , R = radius of large circle of Annulus, r = radius of small circle of Annulus and is represented as P = 2*pi*(R+r) or perimeter = 2*pi*(Radius of large circle+Radius of small circle). Radius of large circle is defied as the outer radius of the given polygon & Radius of small circle is defined as the inner radius of the given polygon.
How to calculate Perimeter of Annulus?
The Perimeter of Annulus formula is defined as sum of all the outermost part of Annulus where , p=2π(R+r) , p = perimeter of Annulus , R = radius of large circle of Annulus, r = radius of small circle of Annulus is calculated using perimeter = 2*pi*(Radius of large circle+Radius of small circle). To calculate Perimeter of Annulus, you need Radius of large circle (R) & Radius of small circle (r). With our tool, you need to enter the respective value for Radius of large circle & Radius of small circle and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Perimeter?
In this formula, Perimeter uses Radius of large circle & Radius of small circle. We can use 4 other way(s) to calculate the same, which is/are as follows -
  • length = 2*sqrt((Radius of large circle^2)-(Radius of small circle^2))
  • area = pi*(Radius of large circle^2-Radius of small circle^2)
  • breadth = Radius of large circle-Radius of small circle
  • perimeter = 2*pi*(Radius of large circle+Radius of small circle)
