So I have summer homework for Combo Physics and I have absolutely no idea how to do this. I have an idea I just don't know how to get the answer given. I would love the help 
The Problem:
An iron sphere has a mass density of p= 7.86 x 10^3 kg/m^3 . Of the sphere has a radius od .5 m, how much mass does the sphere contain? (ans= 4115.3 kg)
I know to find the volume of a sphere is 4/3 x (pie) x r^3
I never get the right answer though. Someone please help me
