The discussion centers around the application of the circumference formula for a sphere, specifically in relation to calculating the circumference from a given radius. Participants explore whether the same formula used for circles can be applied to spheres and seek clarification on the definition of circumference in this context.
While there is agreement on the definition of the circumference of a sphere as that of a great circle, the initial question regarding the application of the formula remains somewhat contested, as the context of the inquiry suggests uncertainty.
The discussion does not resolve the initial participant's uncertainty about the correctness of their calculated circumference, nor does it clarify any potential limitations in the application of the formula.

The circumference is always that of a circle. In the case of a sphere, it is the circumference of a great circle, circles of maximal circumference.Perchaddition said:Just ran numbers in the first circumference calculator I found http://calcurator.org/circumference-calculator/. Can I use the same formula for a sphere? What can I say ...Geometry is not my passion
