About Volume of a Cone

Find the exact volume of a cone given its radius and height. 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 Cone 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 cone expression and receive a complete, verified solution with every step shown.

Volume of a Cone Formula

V = (1/3)πr²h

A cone holds exactly one third of the volume of a cylinder with the same base and height. Use the perpendicular height h from the tip to the base, not the slant height along the side.

Worked Example

Find the volume of a cone with radius 4 cm and height 9 cm

  1. Base area: π × 4² = 16π
  2. Multiply by height: 16π × 9 = 144π
  3. Take one third: 144π ÷ 3 = 48π
  4. Decimal: ≈ 150.80 cm³

Answer: 48π ≈ 150.8 cm³

Common Mistakes to Avoid

  • Using the slant height in place of the vertical height.
  • Forgetting the factor of 1/3.
  • Using the diameter instead of the radius.
