Density is equal to the ratio between the mass and the volume:
ρ = m/V
The volume of a ball (a sphere is not a body) is:
V = 4*π*R^3/3
Calculating the volume, we get:
V = 4*3.14*(1.4 m)^3/3 = 11.5 m^3
Dividing, we get:
ρ = 500 kg/11.5 m^3 = 43 kg/m^3

density=mass/volume
you have the mass 500 kg and the sphere's volume is 4/3multiplied by pi, which is 3.14 multiplied by the radius u have (1.4) power3 (cubed) .
the final answer will be 43.5 kg/m^3

Density = Mass / Volume.
Volume = (4/3) pi r^3
your mass is given
