WebOct 30, 2010 · A "great circle", so called because they are the largest possible circles on a sphere. If you're on a sphere (say, Earth) and you want to go between two points using the shortest path, then a great circle is the path you should follow. This makes them like straight lines for spheres. Or in technical terms, arcs of great circles are geodesics. WebDec 30, 2016 · the real radius of the circle is R sin θ and the circumference of it is therefore c = 2 π R sin θ; the length of the arc drawn on the sphere is R θ: call this r. So r = R θ, or in other words θ = r / R. So the circumference of the circle is given in terms of r by c = 2 π R sin ( r R) And this is valid for θ ∈ [ 0, π] or r ∈ [ 0, π R].
