What is the relationship between the radius and circumference of a circle on a sphere? It’s not of course 2r. For a great circle it is 4r. But as the circle gets smaller it does get closer to 2r. Right? Which seems bizarre. But intuitive.
In hyperbolic geometry the circumference would be greater than 2r. But I can’t find any reference about a circle sphere.
