The center of mass of a sphere is its geometric center.
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
First and foremost, you must know the density. Mass is the product of volumeand density (m=vd). Also, a sphere is specified by its radius alone. The "length"of a sphere should represent nothing more than its diameter, which is twice itsradius.==============================Answer #2:First of all, that's no sphere, since spheres don't have 'length'.Next . . . As written, the question has no answer, simply because the mass ofa sphere doesn't depend on its size. A hundred spheres can easily all have thesame size but a hundred different masses.
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
