learn moreHow to Calculate the Mass of a Sphere: 13 Steps .
· To calculate the mass of a sphere, start by finding the sphere''s volume using the formula: V = 4 over 3 × πr cubed, where r is the radius of the sphere. Once you have the volume, look up the density for the material the sphere is made out of and convert the density so the units are the same in both the density and volume. Finally, multiply the volume by the density to the find the sphere''s mass.
