calculate the volume using the formula:
Vsphere = (4/3)*pi*r^3
then calculate density by
Density = Mass/Volume
You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
First and foremost, you must know the density. Mass is the product of volumeand density (m=vd). Also, a sphere is specified by its radius alone. The "length"of a sphere should represent nothing more than its diameter, which is twice itsradius.==============================Answer #2:First of all, that's no sphere, since spheres don't have 'length'.Next . . . As written, the question has no answer, simply because the mass ofa sphere doesn't depend on its size. A hundred spheres can easily all have thesame size but a hundred different masses.
Volume of a sphere = 4/3*pi*radius3
It's the extension of the sphere's radius drawn to that point.
how do you find the mass of a sphere Volume x density => 4/3(pi)(r)3 x density
you have to divide the mass by the volume then measure the ends then you found your answer
Volume of anything = (its mass) divided by (its density) regardless of what shape it happens to be.
a gold sphere
Density is the mass per unit volume. e.g. kg/m3. But you've only given one of the quantities needed - we still need the volume of the 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.
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
Divide its mass by its volume.
You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]
The mass of a sphere is 4/3*pi*r3*d where r is the radius of the sphere and d is the density of the material of the sphere.
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
