We can calculate the area of a circle by using the formula areacircle pi times r2. We know that pi is about 3.14 and r is the radius of the circle. Πr2
Where:
Π pi (3.14159265...)
r radius of circle
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.
reduction ratio= initial cross sectional area/final cross sectional area
It is the same as that of an area of a circle which is: pi times radius squared.
The volume of a cylinder is the cross-sectional area of the cylinder multiplied by its length. The perpendicular cross-section of a cylinder is a circle.
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.

To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.
Because the volume of the cylinder is proportional to the cross sectional area of the cylinder. The cross sectional area is a circle and the area of a circle is pi*r2.
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.
Simply work out the area of a section of cable.........
It is the same as that of an area of a circle which is: pi times radius squared.
The volume of a cylinder is the cross-sectional area of the cylinder multiplied by its length. The perpendicular cross-section of a cylinder is a circle.
Conversion of cable diameter to circle cross-sectional area and vice versa. Scroll down to related links and look at "Conversion of cable diameter to circle cross-sectional area".
If you slice a wire cleanly and then look at the cut end, you see a little circle at the end. The area of that circle is the "cross-sectional area" of the wire. The larger that area is, the lower the DC resistance of the wire is.
Well, honey, the formula for the cross-sectional area of a coin is just π times the radius squared. So, measure that radius, square it, multiply by π, and voilà, you've got your cross-sectional area. Just don't go spending all that knowledge in one place, now.
