Annulus Sector 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.

Annulus Sector
Ring sector — is a part of a circle bounded by arcs of different radii and two lines of radii drawn to the ends of the curve of a larger radius.
Annulus Sector Area
The area of the annulus sector, as well as the area of the annulus itself, is considered as a difference, only except areas of circles, difference of their larger and smaller sectors. The area of the annulus sector is equal to the product of the number pi, the ratio of the angle of the sector of the annulus to 360 and the difference of the squares of the outer and inner radii of the annulus.
