Likewise, people ask, what is annular domain?
Annular domain. From Encyclopedia of Mathematics. A doubly-connected planar domain between two closed Jordan curves without common points, one of each encloses the other. For an annular domain with respect to a quadratic differential, see Global structure of trajectories of a quadratic differential.
What is the formula for circumference?
The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
