The image above is a sphere. To calculate the volume of a sphere, one essential parameter is needed and this parameter is the radius of the sphere (r). You can also use diameter of the sphere (d).
The formula for calculating the volume of a sphere:
V = (4/3)πr³
Where;
V = Volume of the sphere
r = Radius of the sphere
Let’s solve an example:
Find the volume of a sphere when the radius of the sphere is 10 cm.
This implies that;
r = Radius of the sphere = 10 cm
V = (4/3)πr³
V = (4/3)π x (10)³
Which means that, V = (4/3)Ï€ x 1000
V = (4/3)3.142 x 1000
V = (4/3)3142
Then, V = 1.33 x 3142
V = 4188.7
Therefore, the volume of the sphere is 4188.7 cm³.
Calculating the Volume of a Sphere using Diameter of the Sphere.
V = 4πd³ / 24
Where;
V = Volume of the sphere
d = Diameter of the sphere
Let’s solve an example:
Find the volume of a sphere when the diameter of the sphere is 20 cm.

This implies that;
d = Diameter of the sphere = 20 cm
V = 4πd³ / 24
V = 4 x 3.142 x (20)³ / 24
So, V = 4 x 3.142 x 8000 / 24
V = 100544Â / 24
V = 4189.3
Therefore, the volume of the sphere with diameter is 4189.3 cm3.
Calculating the Radius of a Sphere using Volume of the Sphere.
r = 3√(3V / 4π)
Where;
V = Volume of the sphere
r = Radius of the sphere
Let’s solve an example:
Find the radius of a sphere when the volume of the sphere is 250 cm3.
This implies that;
V = Volume of the sphere = 250 cm3
r = 3√(3V / 4π)
r = 3√(3 x 250 / 4 x 3.142)
That is, r = 3√(750 / 12.568)
r = 3√59.675
r = 3.907
Therefore, the radius of the sphere is 3.907 cm.
Calculating the Diameter of a Sphere using Volume of the Sphere.
d = 3√(24V / 4π)
Where;
AÂ = Area of the sphere
d = Diameter of the sphere
Let’s solve an example:
Find the diameter of a sphere when the volume of the sphere is 40 cm3.
This implies that;
V = Volume of the sphere = 40 cm3
d = 3√(24V / 4π)
d = 3√(24 x 40 / 4 x 3.142)
So, d = 3√(960 / 12.568)
d = 3√76.38
d = 4.24
Therefore, the diameter of the sphere is 4.24 cm.
