What measurements must be entered in the Concrete Column Calculator?

• A. Height and Diameter
• B. Width and Depth
• C. Length and Width
• D. Height and Wall Thickness

Answer: (A)

For a cylindrical concrete column, you need the height (the length of the column) and the diameter (which sets the cross‑sectional area). The volume of a cylinder is the cross-sectional area (πd^2/4) times the height, so these two measurements let the calculator determine how much concrete is required and related quantities. Other dimension pairs correspond to other shapes (width and depth for a rectangular column, wall thickness for a hollow form), not to a round cylindrical column, so they aren’t the inputs used here.
