Concrete Volume Calculator (Cylindrical Form)
This calculator helps you estimate the total volume of concrete needed to fill cylindrical forms such as piers, columns, or pipes. Input the radius, depth, and quantity to calculate the total concrete in cubic yards.
Calculate Concrete Volume for Cylindrical Forms
Cylindrical Concrete Volume Formula
$$\text{Volume} = \left( \frac{22}{7} \cdot r^2 \cdot \text{depth} \right) / 27 \cdot \text{Quantity}$$
Where:
- $$r$$ — radius of the cylinder (feet)
- $$depth$$ — height/depth of the cylinder (feet)
- $$Quantity$$ — number of cylinders
- $$27$$ — converts cubic feet to cubic yards
This calculator is ideal for projects involving multiple cylindrical elements like pillars or footings. It uses the approximation $$\pi \approx \frac{22}{7}$$ and converts the result to cubic yards — the standard for ordering concrete. Great for both contractors and DIYers.
