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.
To calculate Cross Sectional Area: Width x Depth
reduction ratio= initial cross sectional area/final cross sectional area
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
The cross sectional area of a slab can be found by squaring the height of the slab.
To calculate Cross Sectional Area: Width x Depth
reduction ratio= initial cross sectional area/final cross sectional area
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.
Simply work out the area of a section of cable.........
You cannot unless you know the angle of the plane which defines the cross section.
Volume = Cross sectional Area x Height.
Perimeter of the base of the ruler multiplied by its height
measure the channel height and then width and multiply them together
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
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.
