you have to measure the diameter of the coil and then multiply the diamter by pi

Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
To calculate circumference you need to multiply the diameter by pi C= d x pi (3.14) Do the math
kg = 6.16546 x width mm x OD2 x bore2 ---- 1000000
Weight divided by 3.399, divided by gauge. Divided by width.
To calculate the outside diameter of a steel coil, you first need to determine the inside diameter (ID) and the thickness of the steel material. The outside diameter (OD) can then be calculated using the formula: OD = ID + 2 × thickness. If the coil is wound in layers, you may also need to account for the number of layers by adding the thickness multiplied by the number of layers to the ID.
0.7854*r*r*h where r- radius of coil h is height of coil for 3" coil volume is 0.7854*1.5*1.5*2.54*2.54*1.7/10000=2lts
density=mass/volume 7.850=2500kg/(0.47*L*0.914) Ravindra
You know that each 'wrap' or turn of wire in the coil has to go all the way around the coil-form, and you know how to calculate the distance around a circle. So all you have to do is count the number of times the wire goes around the coil, measure the coil's diameter, calculate its circumference, and multiply that by the number of turns in the coil.
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
how do you calculate the circunference of hemisphere?
pi times diameter = circumference
The answer will depend on what is meant by "how do you you do" or even "how do you do". I do not do circumference. A can draw it, I can calculate it, I can calculate other measures (area, radius, diameter) from it but I do not DO it!
