Answer #1:
Mass is the product of volume and density. You can find the volume of a sphere
with a radius of four (regardless of the unit of measure) using v=4/3pi(r3). With
the volume you must multiply by the density to find the mass.
======================================
Answer #2:
As written, the question has no answer, simply because the mass of a sphere
doesn't depend on its size. A hundred spheres can easily all have the same size
but a hundred different masses.

∙ 10y agoDensity = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
Surface area of a sphere = 4*pi*radius squared
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)]
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
Vol = 4/3*pi*r3 so given the volume, you can calculate the radius. Height of sphere = 2*radius.
Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2
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.
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.
The formula with a known radius is: V = 4/3(PI*r3) A sphere with a radius of 4 units has a volume of 268.08 cubic units.
The formula for the volume of a sphere is based on the radius of the sphere. It is equal to 4/3 multiplied by pi, multiplied by the radius cubed.
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 "area of a sphere" does not make sense. You must mean the "volume of a sphere". double radius = ...; double volume = 4. / 3. * 3.141592653589793 * radius * radius * radius;
The area of a sphere is 4 x pi x r2. "r" is the radius.
Surface area of a sphere = 4*pi*radius squared
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)]
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
