Practice problems of the annulus

An annulus is a ring-shaped object, a region bounded by two concentric circles. It is a set of points whose distance from the center of S is between r1 and r2 inclusive, where r1, and r2 are radii. 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
