The volume of a sphere is 4/3*pi*r3
So Vol8/Vol1 = 83/13 = 83 = 512
83 = 512
Gravity pulls with equal strength in all directions; therefore any variations from a spherical shape will lead to gravitational forces that bring the shape back into that of a sphere.
400 mg lead in each kilogram of soil.
A mathematical point is only a location, and has no dimensions. Of course, when you mark the point on paper, it has the same diameter as the lead in your pencil, or the ball on your BIC.
Is this taking into consideration the dross content as the metal melts it oxides? and how much does the lead pipe weigh per foot?

It is: (4//3*pi*83) divided by (4/3*pi*13) = 512
5.94 milligrams.
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.
Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.
d=m/v v= (4/3)(pi)(r^3) set up equation for aluminum and lead 11.3*10^3=m/( (4/3)(pi)(ri^3)) 2.7*10^3=m/( (4/3)(pi)(ra^3)) solve for m. then set two equations equal to each other, since they have the same masses. finally, solve your new equations for ra/ri 11.3*10^3( (4/3)(pi)(ri^3)) =m 2.7*10^3( (4/3)(pi)(ra^3)) =m 11.3*10^3( (4/3)(pi)(ri^3)) = 2.7*10^3( (4/3)(pi)(ra^3)) 11.3*10^3/2.7*10^3 = (ra^3)/(ri^3) (11.3*10^3/2.7*10^3)^(1/3)=ra/ri
2 balls of the same diameter can have the same mass. Equally, they can have a different mass. (i.e Having the same diameter does not automatically mean that they are the same mass).However, they will have the same volume. In maths, volume of a sphere (ball) =4/3*(pi)*radius^3. Hence volume is directly proportional to diameter (radius is half the diameter).Mass is a measure of "how dense something is" (e.g lead, wood and concrete are all dense, whereas meringue and mousse are not) Mass has nothing to do with the size of the ball, only what substance the ball is made up of. Whereas volume is easiest of think of as "how much water can I fit in this" (volume is directly related to the size of the container).Hope that helps, rather than confuses.
There are a lot of things you can do with a ball like playing catch. If the ball is small enough you could play tennis or if it is dense enough, basketball.
The minie ball replaced the lead ball that was used in the American Revolution.
it depends on what the damage is if the earth sphere was completly broken we would have burn from the heat radiaion if the sphere was weak we would life our last few days in the sun hot unough to melt lead
Faulty ball bearings lead to bearing failure.
