weight the metal ball first. then fill a graduated cylinder with water- it doesnt really matter how much, and put the metal ball in the water. measure how much the water level has increased by in mL. take the mass, and divide by the mL of water and then you get the density.

If it's an accurate sphere you can also measure its diameter and so calculate the volume, from which and the mass you can calculate the density.
There are several methods that can be used to calculate the density of a metal ball. The density of a metal ball can be derived from the fact that the volume is: 4*(pi)*r^3/3 and the denisty is mass/volume. If the mass and moment of inertia are known but the dimensions of the metal ball are not, then you can use the fact that the moment of inertia of the ball is 2m*r^2/5 and solve for m to get r=(5I/2)^.5 and plug in the value for r into the volume equation then calculate the density of the ball by dividing the mass by the calculated volume.
Float the ball in water and calculate the displacement.
Unless you can calculate or measure the volume, you cannot. And even if you could you would get the average density - of the material of the ball and the air inside.
A solid metal ball would sink into the very viscous liquid, a hollow metal ball would float. The speed of descent is dependent on the density of the liquid.
3900 what? Unanswerable - not enough information.
Density = (mass) / (volume)= (357 gm) / (3.01 cm)3= 13.091 gram per cm3
Every metal has a density.
Low Density a Metal?NO!!!!
Determine the mass, and then put the ball bearing in a known amount of water, and see what the increase in volume is (using cm3 or mm). Then do Mass divided by Displased Water, and you have density.
No shape can have a density of 7.2 g since grams are not unit in which density is measured.If the density were 7.2 grams per cubic centimetre, then the with would be approx 0.000476 cm = 4.76 micrometres.
Low Density a Metal?NO!!!!
It describes things that have a higher density than another object. For example, "The metal ball is denser than the baloon."
