About Volume of a Sphere
Calculate the 3D volume of a spherical object. Geometry explores the properties and relationships of shapes, sizes, and dimensions. From basic triangles to 3D solids, geometric formulas are used in engineering, architecture, and physics.
Our Volume of a Sphere calculator handles every type of problem in this topic. Whether you are a student working through homework, preparing for an exam, or a professional needing a quick calculation, you can enter any volume of a sphere expression and receive a complete, verified solution with every step shown.
Volume of a Sphere Formula
V = (4/3)πr³
The volume of a sphere depends only on its radius, cubed. Because the radius is cubed, doubling the radius makes the volume eight times larger. Answers are in cubic units.
Worked Example
Find the volume of a ball with radius 3 cm
- Cube the radius: 3³ = 27
- Multiply by 4/3: (4/3) × 27 = 36
- V = 36π cm³
- Decimal: ≈ 113.10 cm³
Answer: 36π ≈ 113.1 cm³
Common Mistakes to Avoid
- Squaring the radius instead of cubing it.
- Using the diameter in the formula.
- Confusing volume with surface area (4πr²).
