Density of sphere formula
WebNov 27, 2015 · Your formula of mass = volume × density needs to be a bit modified here since the density is non-uniform. Every bit of volume of the sphere has a different density so you have to integrate it appropriately as follows: M = ∫ 0 1 density ⋅ d V = ∫ 0 1 ( 1 − r 2) ⋅ d V and we know that V = 4 3 π r 3 where r is the radius of the sphere WebMay 2, 2024 · $\begingroup$ The sphere in the question is solid, but think of it as being made up of many hollow concentric spherical shells, each shell being $ \delta r$ thick. Each shell has uniform density and for the shell …
