Consider the volume of the pipe as the difference in the volume of two cylinders, one containing the whole pipe and the other the empty space inside. Use the formula for the volume of a cylinder : Pi*r*r*h. Find the volume of the first cylinder with the larger radius and subtract from it that of the cylinder with the smaller radius. The height (or length) is the same for both volume calculations. The result of subtracting these is the volume occupied by the pipe.
measure the radius of the pipe. (half the diameter - the width of the pipe) then measure the length of the pipe. then use the formula pi (3.14) x radius2 x length. the answer is the volume in the pipe
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).
You need to know the pipe's radius (1/2 diameter) as well as the length. Then, use this formula: Volume = radius2 x pi x length
what is the radius? It depends on the the radius. Formula 3.14*radius squared*5=answer
