Write (T) for True and (F) for false:
(v) A sphere has a curved surface.

Answer

To determine whether the statement "A sphere has a curved surface" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Sphere**:
- A sphere is a three-dimensional shape that is perfectly round, similar to a ball or a globe.

2. **Identify the Characteristics of a Sphere**:
- A sphere has all points on its surface equidistant from its center. This means that it does not have any flat surfaces.

3. **Examine the Surface of a Sphere**:
- The surface of a sphere is smooth and round, which means it does not have any edges or corners.

4. **Conclude about the Surface**:
- Since a sphere is defined as having a smooth, round surface without any flat areas, we can conclude that it indeed has a curved surface.

5. **Final Answer**:
- Therefore, the statement "A sphere has a curved surface" is **True (T)**.
