To measure the circumference of a piece of pipe, you should use a _______________.

AI Explanation
The correct answer is C) flexible steel rule. To measure the circumference of a pipe, a flexible steel rule is the appropriate tool to use. A flexible steel rule can easily wrap around the curved surface of the pipe, allowing you to accurately measure the circumference. In contrast, a folding rule (option A), hook rule (option B), or machinist's steel rule (option D) would not be able to conform to the curved shape of the pipe, leading to an inaccurate measurement.
