Best Answer

The density of lead is well known; you can look it up in any reference book on chemistry, or on the internet. It is 11.34 grams per cubic centimeter, according to Wikipedia. But if you have a sphere that is only part lead, you can get the density of the sphere by weighing it, and dividing the weight by its volume. The volume of a sphere is 4/3 x pi x r ^ 3, where r is the radius of the sphere.

mass over volume

calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume

Measure the diameter and from that calculate the volume, then determine the mass of the sphere on a weighing device. Then it's just density = mass/volume ========================== It again depends on the sphere whether its hollow or its a solid sphere

Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.

Weigh it, calculate its volume, then calculate density.

The sphere made from the least dense material. If this is for a specific math problem, you may have to calculate density by dividing mass / volume for each sphere. The question could be about the "four spheres of the Earth" : Atmosphere Biosphere Hydrosphere Lithosphere. In that case the answer is the "atmosphere".

Divide its mass by its volume.
