Use the formula for a cylinder to find out the volume. Then multiply the volume by the density of steel (about 7900 kg/m3 - but it may vary slightly depending on the type of steel).
Since we want to calculate the weight of a cylinder, the formula is W = V*D. Or, Weight = Volume*Density. [πr²h is the formula for volume. Pi [3.14159...] x radius squared x height. Simply substitute if you have all aspects of the formula.]
What is density?? Density = Weight / Volume. So if the density and weight are given, you can easily find the volume of diesel.
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
How do you calculate steel weight without using steel table book?

kg = 6.16546 x width mm x OD2 x bore2 ---- 1000000
by using calculator
formula calculation of steel round bar > Area (square metres) of cross section * 7850 = kilograms per metre length. For other lengths, multiply answer by length in metres.
Calculate the empirical formula weight. Find the ratio of the molecular weight to the empirical formula weight. (n= molecular weight/ empirical formular weight). Multiply each subscript of the empirical formula by n.
