To calculate the weight of a 30-foot piece of 3-inch diameter aluminum pipe, you first need to determine the volume of the pipe and then multiply it by the density of aluminum, which is approximately 0.0975 pounds per cubic inch. The volume of the pipe can be calculated using the formula for the volume of a cylinder: ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height (or length of the pipe). A 3-inch diameter pipe has a radius of 1.5 inches, so the volume is roughly 211.3 cubic inches, resulting in a weight of about 20.6 pounds for a 30-foot length.
