Mass of a sphere given density and radius

The density of mass inside a solid sphere of radius a is given

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. WebWe can calculate the density of a spherical object if we know the mass of the sphere, 𝑀, and the radius of the sphere, 𝑟. If we know these quantities, then we can use the equation for density, which is 𝜌 = 𝑀 𝑉, along with the equation for the volume of a sphere, which is 𝑉 = 4 3 𝜋 𝑟.
