If A and B are two points on a circle of radius R and center C, then the length of the arc of the circle connecting them is given by
d(A,B) = R a,
where R is the radius of the sphere, and a is the angle ACB measured in radians. If we measure the angle in degrees, then the formula is
d(A,B) = R a/180,
d(A,B) = R a,
where R is the radius of the sphere, and a is the angle ACB measured in radians. If we measure the angle in degrees, then the formula is
d(A,B) = R a/180,
