## Code Annotations


```python
def calculate_area(radius: float) -> float:  # (1)!
    """Calculate the area of a circle."""
    import math  # (2)!
    return math.pi * radius ** 2  # (3)!
```

1. Type hints improve code readability
2. Import inside function for demonstration
3. Uses the formula: A = pi * r^2
