State whether true (T) or false (F) :
A cylinder has two flat faces .

Answer

To determine whether the statement "A cylinder has two flat faces" is true or false, let's analyze the properties of a cylinder step by step.

### Step 1: Understand the Shape of a Cylinder
A cylinder is a three-dimensional geometric shape that has two circular bases connected by a curved surface.

**Hint:** Think about the basic structure of a cylinder. What shapes make it up?

### Step 2: Identify the Faces of a Cylinder
A cylinder has:
- **Two circular faces** (the top and bottom bases).
- **One curved surface** that wraps around the sides.

**Hint:** Consider how many distinct surfaces you can identify on a cylinder.

### Step 3: Determine the Nature of the Faces
The two circular bases are flat surfaces, while the curved surface is not flat.

**Hint:** Recall the definition of flat surfaces. Are circular surfaces considered flat?

### Step 4: Conclusion
Since a cylinder has two flat circular faces, the statement "A cylinder has two flat faces" is **True (T)**.

**Final Answer:** True (T)
