Calculating the volume of a tube essentially involves the same formula as a cylinder volumepr 2 h except that in this case the diameter is used rather than the radius and length is used rather than height. PI B5 2 C5. Volume of a cylinder formula.
The formula therefore involves measuring the diameters of the inner and outer cylinder as shown in the figure above calculating each.
I seem to have run in to a problem with an assignment part A- Having radius r18 and height h115 Calculate volume of cylinder V1 formula vpir2h r18 h115 V1pir12h1. Now heres the problem Part B- Using h1 from part A find radius r2 of another cylinder V2 that has a volume greater by 20 than that of V1. The formula for the volume of a cylinder is height x p x diameter 2 2 where diameter 2 is the radius of the base d 2 x r so another way to write it is height x p x radius 2. To calculate the volume of a cylinder you need to know its height and the area of its base.
