What is the length of a cylinder if its height is given as 20 inches?

• A. 15 inches
• B. 20 inches
• C. 25 inches
• D. 30 inches

Answer: (B)

In the context of the question posed, the "length of a cylinder" is typically interpreted as the height of the cylinder when no other dimensions are specified. A cylinder is defined by its height (or length) and its radius. Here, the height of the cylinder is provided as 20 inches. Therefore, the length that corresponds to the height of the cylinder is indeed 20 inches. This is consistent with how dimensions are generally defined in geometry; the height of a vertical cylinder is often referred to as its length. In practical terms, if you were to measure the cylinder from its base to its top, you would find that this dimension is 20 inches, aligning perfectly with the height given in the question.
