Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
Other things being equal, more cross-sectional area will cause less resistance.
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.

You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
the larger the cross sectional area, the smaller the resistance
direct stress is based on the value obtained by dividing the load by originalcross-sectional area. That is the reason why the value of stress started dropping after neck is formedin mild steel (or any ductile material).But actually as material is stressed itscross-sectional area changes. We should divide load by the actual cross-sectional area to get truestress in the material. To distinguish between the two values we introduce the terms nominal stress and true stress True Stress =Load/ActualCross-sectionalArea Nominal Stress =Load/Original Cross-sectionalArea
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
The cross sectional area of a slab can be found by squaring the height of the slab.
Cross Sectional Area = Width x Average Depth
cross-sectional area = 0.5*(sum of parallel sides)*height
reduction ratio= initial cross sectional area/final cross sectional area
A Y12 bar typically has a cross-sectional area of 113 square millimeters.
cross sectional area of cable * voltage drop
The resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that as the cross-sectional area of the wire increases, the resistance decreases, and vice versa.
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
