1. Let's clarify the problem: You asked "How is the hole a cylinder?" which suggests you want to understand why a hole can be considered a cylindrical shape. 2. A cylinder is a 3D shape with two parallel circular bases connected by a curved surface. It looks like a tube or pipe. 3. When we talk about a hole, especially one drilled or cut through an object, it often has a circular cross-section and extends straight through the material. 4. This shape matches the definition of a cylinder because the hole has two parallel circular openings (the entry and exit points) and the sides of the hole form a curved surface inside the material. 5. Therefore, the hole is a cylinder because it is a 3D shape with circular cross-sections and a consistent shape along its length. Final answer: A hole is a cylinder because it has two parallel circular faces and a curved surface connecting them, matching the geometric definition of a cylinder.
