Volume = (4/3) × π × r³The volume of a sphere is four-thirds times pi times the radius cubed.
Where:
r= Radius of the sphereπ= Pi, approximately 3.14159Surface Area = 4 × π × r²The total surface area of a sphere is four times pi times the radius squared.
Where:
r= Radius of the sphereπ= Pi, approximately 3.14159Inputs
Result
Volume = (4/3) × π × 5³ = (4/3) × π × 125 = 523.60. Surface Area = 4 × π × 5² = 4 × π × 25 = 314.16. Diameter = 2 × 5 = 10.00.

Result
Volume = (4/3) × π × 3³ = (4/3) × π × 27 = 113.10. Surface Area = 4 × π × 3² = 4 × π × 9 = 113.10. Diameter = 2 × 3 = 6.00.
Volume of a sphere = (4/3) × π × r³, where r is the radius. For example, a sphere with radius 5 has volume = (4/3) × π × 5³ = 523.60 cubic units.
| Radius | Volume | Surface Area | Diameter |
|---|---|---|---|
| 1 | 4.19 | 12.57 | 2 |
| 2 | 33.51 | 50.27 | 4 |
| 3 | 113.10 | 113.10 | 6 |
| 5 | 523.60 | 314.16 | 10 |
| 10 | 4,188.79 | 1,256.64 | 20 |
Surface area of a sphere = 4 × π × r², where r is the radius. For a sphere with radius 5, surface area = 4 × π × 5² = 314.16 square units.
Diameter = 2 × radius. The diameter is twice the radius. If radius is 5, diameter is 10. The radius is half the diameter.
Yes, first find the radius: radius = diameter / 2, then use the volume formula: V = (4/3) × π × r³. Alternatively, V = (4/3) × π × (d/2)³ = (π × d³) / 6.
| Shape | Volume Formula | Volume (r=5) |
|---|---|---|
| Sphere | (4/3)πr³ | 523.60 |
| Cylinder (h=2r) | πr² × 2r = 2πr³ | 785.40 |
| Cone (h=2r) | (1/3)πr² × 2r | 261.80 |
| Cube (side=2r) | (2r)³ = 8r³ | 1,000.00 |
A sphere is a perfectly round 3D shape where all points on the surface are equidistant from the center. All calculations depend on the radius.
The volume formula is (4/3)πr³, and the surface area is 4πr². These are fundamental formulas in geometry.
The diameter is always twice the radius, making it easy to convert between the two measurements.
