Annulus Area
Area
Area is a numerical characteristic of a two-dimensional (flat or curved) geometric figure, informally speaking, showing the size of this figure. Historically, the calculation of the area was called quadrature. A figure having an area is called quadratic. Find the area of more than 22 shapes (triangle, square, pentagon, etc.) using our amazing calculator.
Annulus
Ring — is a flat geometric figure bounded by two concentric circles. An open ring is the topological equivalent of a cylinder and a punctured plane.
Annulus Area
The area of the annulus, in fact, is the area of the big circle minus the area of the small circle, so to find area of a annulus, we will use circle area formula.
