4*Pi*R squared, it may seem like a hard formula, but if you think about it it is pretty easy to understand.
There are many ways to do it, but to me the easiest way to do it is to square the radius ( half of the distance from the other point of a circle) then multiply it by Pi then multiply it by 4.
Example:
Radius= 2cm.
R squared is 4 cm. (2*2) multiplied by pi equals 12.56 (pi=3.14) then multiply that by 4 to get your final answer which is 50.24.

Not only is the formula hard, it is completely wrong!
The volume of a sphere is 4/3*pi*R3 where R is the radius.
Because it is a measure of the volume, the linear measures appearing in it MUST be to the third power (cubed). Thus, the fact that the previous answer gave R2 was a clear indication of an error. The example then multiplies by R2 twice making it R4!
volume of the cube - volume of the sphere = volume enclosed between the cube and sphere
The volume of a sphere with a radius of 4cm is about 268cm3
The volume of a sphere with a radius of 2cm is about 33.5cm3
A sphere with a radius of 24 cm has a volume of 57,905.84 cm3
The volume inside a sphere (that is, the volume of the ball) is given by the formula:-Volume = 4/3πr3where 'r' is the radius of the sphere and 'π' is the constant piThe diameter of a sphere is two times its radius, thus a sphere 8 meters in diameter has a radius of 4 meters.
volume of the cube - volume of the sphere = volume enclosed between the cube and sphere
The volume of a sphere is the amount of space it occupies. Given a sphere's radius, r, the volume is 4/3 ∏r3
A sphere with a radius of 7cm has a volume of 1,436.76cm3
Volume of this sphere is 4,188,790 cm3
The volume of a sphere is 4 / 3 * pi * r3
The volume of this sphere is 113,097 cubic units.
Volume of a sphere = 4/3*pi*radius3
Volume of a sphere = 4pi*r^3 2r = d, so Volume of a sphere = 4pi*(4)^3 Volume = 256pi
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 water displacement of a sphere can be calculated using the formula for the volume of a sphere, which is V = (4/3)πr^3, where r is the radius of the sphere. The volume of water displaced by the sphere is equal to the volume of the sphere when it is submerged in water.
The volume of the 6 cm sphere is 1.53 = 3.375 times as large.
A sphere with a radius of 7 inches has a volume of 1,436.76 cubic inches.
