What this tool does
A cone holds exactly one third of the cylinder that would enclose it, which is worth remembering when estimating a stockpile of sand or gravel. The slant height is also given, since that is the measurement you can actually reach with a tape on a real heap.
Formula
V = (1/3) × π × r² × h

Limitations
- Mixing units is the most common source of error. Convert every input to the units shown next to each field before calculating.
- The result is an estimate based only on the values you type. Real situations often include factors this calculator does not know about.
