About Cone Volume Calculator
The Cone Volume Calculator uses the formula V = (1/3) × π × r² × h, where r is the base radius and h is the height. It uses the built-in value of π for the constant.
Enter the radius and height in matching units and the result is returned in cubic units, rounded to four decimal places. Negative dimensions are not allowed.
Formula & Mathematical Calculation
Volume = f(Radius, Height)
Calculated according to standard math formulas implemented in the calculator core.
Calculation Example
With a radius of 3 and a height of 5, the volume is (1/3) × π × 3² × 5 = π × 15 ≈ 47.1239.
Key Benefits
- Uses the built-in value of pi rather than a manually rounded approximation.
- Returns the volume rounded to four decimal places.
- Rejects negative radius or height values.
- Free and runs in the browser with no sign-up.
How to Use this Calculator

Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
- Results use standard published formulas and account only for the values entered above.
- Rounding is applied for display; the underlying calculation uses your full precision.
- Results are returned in the same units you enter, unless the tool states the output unit.
What it does not cover
- Cone Volume Calculator produces a calculated result for reference and learning, not a certified or official measurement.
- Real-world outcomes differ when tolerances, rounding rules or local standards apply.
- Definitions and standards vary by region and change over time; verify the convention that applies to your case.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For work where the result carries real consequences, confirm it against an authoritative source.
