HINT: An easy way to draw a perpendicular circumference around a large pipe is to wrap a length of material such

as chart paper around the pipe, aligning the edges of the paper precisely at the overlap. With the edge of the chart

paper being parallel, either edge describes a circumference around the pipe that is perpendicular to the pipe axis.

Mark the chart paper exactly where it overlaps. Then, after removing the paper from the pipe, fold the measured

length in half keeping the edges parallel. The fold line now marks a distance exactly half way around the pipe.

Put the paper back on the pipe and use the fold-line to mark the opposite side of the pipe.
