An annulus is a plane figure formed between two concentric circles (the circles sharing a common center). The shape of the annulus is like a ring. Some of the real-life examples of annulus shape are finger-ring, dough-nut, a CD, etc. Let us learn its meaning in terms of geometry along with the area formula and solved examples based on it.
In mathematics, an annulus (pl.: 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).
An annulus is an inner region between two concentric circles i.e. two or more circles sharing the same center point. The annulus is shaped like a ring and has many applications in mathematics that we will be learning in this article. Some of the real-life examples are a doughnut, finger rings. etc.
: a part, structure, or marking resembling a ring: such as. a. : a line of cells around a fern sporangium that ruptures the sporangium by contracting. b. : a growth ring (as on the scale of a fish) that is used in estimating age. Examples of annulus in a Sentence.
Aug 3, 2023 · An annulus is a flat, ring-shaped structure made out of 2 circles. Another way of looking at it is a circular ring with a circular hole in it. Mathematically, it is the area between the 2 circles having a common center (concentric circles) lying in the same plane.

noun. ( Extractive engineering: Field development, Drilling) An annulus is the space between two concentric objects (= objects of the same shape in which a larger one surrounds a smaller one), for example, between the wellbore and casing.
An annulus (meaning little ring in Latin) is a ring-shaped figure between two concentric circles. Below are two examples. Think of an annulus as a circle with a concentric hole in it. An annulus is something you've probably seen in your everyday life.
