How do you work out the cross-sectional area of a wire?
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)
How do you calculate the cross sectional area of cable?
Simply work out the area of a section of cable.........
How do you find the height of a cylinder without the height?
It is possible, depending on what you do know. If you have the radius, you can work out the cross sectional area. Measure the volume - by the displacement method. Then volume/cross section = height.
How many tons per linear meter of steel?
That would depend on the cross sectional area of that linear meter of steel and as you have not told us that we can not answer you. To work out the answer for yourself you need to know the VOLUME of your steel and you multiply this by the density of your steel to give you a weight.
How do you find the volume of a cylinder using lateral surface area and height?
You have to work out the area of the cross section (the circle at the top) So if lateral surface area (LSA) is 2*pi*r*height rearrange to work out the radius (height = LSA/2/pi/r) then use pi * r2 to work out the area of the cross section then times the area of the cross section by the height Overall, this yields the formula: Volume = pi*r2*LSA/2/pi/r = r*LSA/2
