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.


Which element has a larger atomic radius silicon or lead?

Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.


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


Can 2 balls with the same diameter have the same mass?

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.


What sport do you play with a lead ball?

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.
