What is the volume of 16mm pipe?

To calculate the volume of a 16mm pipe, you first need to determine its dimensions, specifically its length and whether it has a solid or hollow structure. Assuming it's a hollow cylinder, the volume can be calculated using the formula ( V = \pi r^2 h ), where ( r ) is the radius (8mm for a 16mm diameter) and ( h ) is the length of the pipe. If you provide the length, the volume can be accurately determined.
