The center of mass of a sphere is its geometric center.
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.
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
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.
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
how do you find the mass of a sphere Volume x density => 4/3(pi)(r)3 x density
Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2
you have to divide the mass by the volume then measure the ends then you found your answer
The center of mass of a sphere is its geometric center.
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 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.
Volume of anything = (its mass) divided by (its density) regardless of what shape it happens to be.
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.
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 density of a sphere can be calculated by dividing the mass of the sphere by its volume. The formula for the volume of a sphere is (4/3)πr^3, where r is the radius of the sphere. By knowing the mass of the sphere and its volume, you can determine its density as mass divided by volume.
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 = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
