pi*radius^2 or since you'll most likely measure a diameter pi*(d/2)^2

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 work out the cross sectional area of a trapezoidal prism?

cross-sectional area = 0.5*(sum of parallel sides)*height


What is function of dial vernier caliper?

A vernier calliper is used to measure the diameter of a wire so that you can work out its cross-sectional area using the formula for the 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.


What length of a copper wire 0.800-melimmeter in diameter has a resistance of 100 ohm?

Work it out for yourself. The equation you will need to use is: resistance = resistivity x (cross-sectional area / length) Manipulate the equation to make 'length' the subject, and use 17.25 x 10-9 ohm metres as the value of resistivity.


How do you calculate the weight of reinforced cement concrete?

as every size bar differ in diameter and possibly type, the reinforcement steel is measured in kilograms per meter, say 8.5kg/m. the steel weight is actually calculated, as a % of the cross-sectional area. different applications have different minimum % steel required, roughly work on 1%. the sum of the bars cross sectional area at each support and spans are seperately calculated and compared to the cross sectional area of the concrete, hence expressed as a %.


How do you Calculate the diameter of a welding wire to kg?

To work out the mass of wire you need to know its volume. The wire is circular so that volume would just be the cross sectional area (pi * r^2) multiplied by the length of wire. Lets call the length L. The equation is then volume = pi * radius^2 * L. To get the mass of the wire we now multiply this equation by denstiy of the wire; that is how much the wire weighs per volume. Assuming the wire is steel this would be around 800Kg/m^3. So what you want to do is work out the volume as above, then multiply by 800, making sure that your units are consistant....ie lenght and radius in metres.


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 can you work out the area of a cross?

Treat it as 3 rectangles.


What is 41.3 cfm converted to meters per second?

CFM is a Volumetric Flow Rate while m/s is a velocity, you need the additional measurement of the Cross Sectional Area of the flow to fully work it out.Since there are 2118.88 CFM : 1 m3/s41.3 CFM divided by 2118.88 = 0.01949 m3/sDivide this by the area in m2 & you will get m/s.


What is a meant by cross section?

Imagine that you wanted to cut a globe or a sphere exactly in half. When you looked at the cut you would see an exact circle on both pieces. This area would be the cross-section. You could work out the area of this cross-section by using A = Pi X r squared. But be careful. Don't assume that the cross sectional area is the same no matter where you cut. If you cut the globe at some other point, say near to the edge, the cross-section (the circular area that you would see) would be a lot smaller. You would come across a uniform cross-section if you cut a cable. No matter where you cut the cable the cross-section should be roughly the same. Also cross section doesn't have to be circular. The cross-section you get really depends on the original shape you are dealing with. If you cut a cube in half, you would get a square cross-section. So I guess you could imagine the term as applying to cutting across (hence cross) something to reveal 2 sections (hence section).
