There is no equivalence. An angle is a measure of rotational displacement. It is formed by two rays (or lines) and does not create an enclosed space. An area is a measure of an enclosed space.
You cannot unless you know the angle of the plane which defines the cross section.
Simply work out the area of a section of cable.........
by calculating I=1/12bh3
Imagine the wire is straight, now cut through at right angle to the centre line, the exposed surface is the cross sectional area, on a round wire it = pi * radius2 (area of a circle)
Perimeter of the base of the ruler multiplied by its height
To calculate Cross Sectional Area: Width x Depth
You cannot unless you know the angle of the plane which defines the cross section.
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.
reduction ratio= initial cross sectional area/final cross sectional area
Simply work out the area of a section of cable.........
by calculating I=1/12bh3
Imagine the wire is straight, now cut through at right angle to the centre line, the exposed surface is the cross sectional area, on a round wire it = pi * radius2 (area of a circle)
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 don't. You can calculate iits radius and cross-sectional area but its diameter has insufficient information to calculate its length
The 45 degrees is an angle. To calculate an area the length and width are needed.
