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.
