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.
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.
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 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 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 "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
