What is the weight of a cylinder with the radius being 0.875 and the height being 5.25?

I know that weight = mass * acceleration of gravity, but I don't know how to find the mass. Can someone explain?

kenljw · Answer

the volume of the cylinder is 
V = 2 pi r X h  = 2 pi .875X5.25 = 9.1875 pi = 28.863
to find the weight you need the density of the cylinder in the same units as the volume.

All I had to do is read further on in the problem and it told me the weight. Thanks though :)
