Consider the following region shown in green:
It is a part of the annular cylinder with the inner radius $R$ and the outer radius $R+r$, which is cut off from the left and right. Is it possible to get this figure as a Region
in Mathematica? For the test parameters, we may consider its longitudinal length dz = 10
, the radii R = 10
, r = 2
, and the transverse length of the remaining shell dx = 2
.
