To solve the problem of finding the radius of the given circle, we should first identify the center of the circle and then determine the distance from the center to any point on the circumference, which is the radius.

### Step-by-Step Solution:

1. **Identifying the Center:**
   The center of the circle is labeled as point \( C(3, 1) \).

2. **Using Point \( P \) to Find the Radius:**
   The point \( P \) is on the circumference of the circle, and the distance \( PC = 5 \). Since \( PC \) is a radius of the circle, the radius of the circle is equal to 5.

Thus, the radius of the given circle is **5**.

### Conclusion:

The correct answer is:
- **Option 4: 5**
