How many balls each of radius 1 cm can be made from a solid sphere of lead of radius 8 cm?

It is: (4//3*pi*83) divided by (4/3*pi*13) = 512

How many lead ball each of radius 1 cm can make a sphere of radius 8 cm?

The volume of a sphere is 4/3*pi*r3 So Vol8/Vol1 = 83/13 = 83 = 512

How do you calculate the density of lead in a sphere?

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.

A uniform lead sphere and a uniform aluminium sphere have the same mass what is the ratio of the radius of aluminium sphere to the radius of the lead sphere?

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
