WebHowever, to find the center of mass of a sphere requires three integrals, one for each coordinate. Each of those integrals will look like the one you wrote down. x ¯ = 1 M ∫ S ρ x d A. y ¯ = 1 M ∫ S ρ y d A. z ¯ = 1 M ∫ S ρ z d A. The limits of integration will have to cover the whole sphere so if you use spherical coordinates ...
