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
Thank you. Appreciate your explanation.fresh_42 said:Yes.

Yes, you can use the circle circumference formula (C=2πr) for a sphere. However, you must use the diameter of the sphere as the radius in the formula.
A sphere has a curved surface, unlike a circle which has a flat surface. The radius of a sphere is measured from the center to the edge, while the diameter is measured from one edge to the opposite edge passing through the center. Therefore, using the diameter in the formula takes into account the curved surface of the sphere.
Yes, there is a specific formula for finding the circumference of a sphere. It is C=2πr, where r is the radius of the sphere. This formula takes into account the curved surface of the sphere and is more accurate than using the circle circumference formula.
Yes, you can use the circle circumference formula for any size sphere. As long as you use the diameter as the radius in the formula, it will give you an accurate result.
Yes, there is another formula called the spherical circumference formula. It is C=2πR, where R is the radius of the sphere. This formula takes into account the thickness of the sphere's surface and is used in more advanced calculations.
