Mass of a sphere given density and radius

WebThe density of mass inside a solid sphere of radius a is given by ρ=ρ 0a/r, where ρ 0 is the density at the surface and r denotes the distance from the centre. Find the … Web1 Answer Sorted by: 2 No. The radius r goes from zero to R . The mass distribution is spherically symmetric, and we want to sum together the masses of the spherical layers. At radius r the density is ρ ( r) and the volume of a thin layer of thickness d r is 4 π r 2 d r . Thus M = ∫ 0 R ρ ( r) 4 π r 2 d r.
