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
The formula for calculating the charge density of a sphere is Q / V, where is the charge density, Q is the total charge of the sphere, and V is the volume of the sphere.
To find the radius of the aluminum sphere, you need to know its density. Without density information, it's not possible to calculate the radius just from the mass given.
The surface charge density formula of a sphere is Q / 4r, where is the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
The charge density formula for a sphere is Q / V, where is the charge density, Q is the total charge, and V is the volume of the sphere.
Volume of anything = (its mass) divided by (its density) regardless of what shape it happens to be.
The density of aluminum is about 2.7 g/cm³. To find the radius of the sphere, you first need to calculate the volume of the sphere using the mass and density formula (volume = mass/density). Next, use the formula for the volume of a sphere (4/3 * π * radius^3) to solve for the radius.
The formula for calculating the surface charge density of a sphere is: Q / 4r, where represents the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
a gold sphere
To find the volume of the sphere, you need to know the density of the material the sphere is made of. With just the mass provided (75 grams), you cannot calculate the volume without this additional information.
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.
