Volume of a sphere = 4/3*pi*radius3
Surface area of a sphere = 4*pi*radius2
Provided they are the same thickness, the larger sphere will have a radius of 10.165cm
To find the volume of a marble, you would use the formula for the volume of a sphere, which is V = (4/3)πr^3, where V is the volume and r is the radius of the marble. Measure the diameter of the marble and divide it by 2 to get the radius. Then, plug the radius into the formula to calculate the volume of the marble in cubic units.
Its diameter is 2R, whatever the mass.
I believe it is I = mk^2 where k is radius of gyration and m is mass.
Density = Mass/Volume so Volume = Mass/Density. Therefore the Volume can be calculated. Volume = Area [of cross section] * Width So Width = Volume/Area.
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.
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.
The moment of inertia of a solid sphere is given by the formula (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
Not sure how a radio can help. If you are given the radius (including units) of a sphere, the volume is 4/3*pi*r3 cubic units. Then mass = density*volume, in the appropriate units.
you need the mass and radius of the sphere- density = mass divided by volume, so mass/volume. the volume of a sphere is 4 divided by 3 multiplied by pi multiplied by the radius squared. 4/3(π)(r^2).
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.
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.
To find the density of the nucleus, we first need to calculate the volume of the nucleus. The volume of a sphere is given by V = 4/3 * π * r^3, where r is the radius of the nucleus. Once we have the volume, we can divide the mass of the nucleus (which is equal to the atomic mass) by the volume to find the density. Density = mass / volume. Substituting the given values, we can calculate the density accordingly.
To find the mass of a sphere, you need to know its density in addition to its volume. The volume ( V ) of a sphere can be calculated using the formula ( V = \frac{4}{3} \pi r^3 ). For a sphere with a radius of 4 cm, the volume would be approximately 268.08 cm³. If you provide the density of the material the sphere is made of, the mass can be calculated using the formula ( \text{mass} = \text{density} \times \text{volume} ).
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
Vol(3)/Vol(2.5) = 33/2.53 = 1.23 So Mass(3) = 1.23*Mass(2.5) = 1.23*500 = 864 grams
Provided they are the same thickness, the larger sphere will have a radius of 10.165cm
