Round / Circular Column Concrete Calculator
For circular columns: enter the diameter and the column height, then the volume follows <code>V = π/4 × d² × h</code>.

METHOD
Circular column volume
V = π/4 × d² × h × n.- Volumetric method: volume = cross-sectional area × thickness, the standard basis for concrete quantity take-off.
- Waste allowance and density are empirical values; verify them against the project specification and the approved mix design.
