Most rebar (steel reinforcement bar) is approximately round.
Measure the diameter of the bar, that is, the thickness of the bar.
Divide the measurement by 2 to get the radius.
Use the formula pi x r2 (3.14 x radius x radius) to get the cross sectional area. The formula works for all measurement units whether they are inches, millimeters, centimeters or others.
An alternative is to use (pi x d^2)/4. (3.14x diameter x diameter divided by 4) You do not then need to divide the original diameter.

How do you calculate cross sectional area?
To calculate the cross-sectional area of a shape, you need to determine the shape of the cross-section first (e.g., square, circle, triangle). Then, use the appropriate formula for that shape. For example, the formula for the cross-sectional area of a square is side length squared, for a circle it is pi times the radius squared, and for a triangle it is base times height divided by 2. Finally, plug in the given dimensions into the formula to calculate the cross-sectional area.
Cross sectional area of concrete slab?
The cross-sectional area of a concrete slab is the total area of the slab when viewed perpendicular to its length and width. To calculate the cross-sectional area, you multiply the length of the slab by the width of the slab. This measurement is crucial for determining the amount of concrete needed for a project and for ensuring the structural integrity of the slab.

How do you calculate velocity in a pipe?
To calculate velocity in a pipe, you can use the formula: velocity flow rate / cross-sectional area of the pipe. The flow rate is the volume of fluid passing through the pipe per unit time, and the cross-sectional area is the area of the pipe's opening. By dividing the flow rate by the cross-sectional area, you can determine the velocity of the fluid moving through the pipe.
