To calculate the amount of concrete needed to fill a 50-foot long, 6-inch diameter pipe, first determine the volume of the pipe. The formula for the volume of a cylinder is ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height (or length). The radius of a 6-inch pipe is 3 inches (0.25 feet), so the volume is approximately ( V = \pi (0.25^2)(50) ), which equals about 9.82 cubic feet. Thus, you would need approximately 9.82 cubic feet of concrete to fill the pipe.
