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 Cross Sectional Area: Width x Depth
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.
= area of a circle = pi*r^2 or length x width if the cross section is longitudinal (since the area will be rectangular)
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.
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.
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.
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".
You cannot unless you know the angle of the plane which defines the cross section.
= area of a circle = pi*r^2 or length x width if the cross section is longitudinal (since the area will be rectangular)
