*Steps of the Algorithm:*
1. **Import Math Module**: Import the `math` module to access mathematical functions and constants.
2. **Prompt User for Radius**: Use the `input()` function to prompt the user to enter the radius of the circle.
3. **Convert Input to Float**: Convert the input string to a float using the `float()` function.
4. **Calculate Area**: Use the formula `area = math.pi * radius ** 2` to calculate the area of the circle.
5. **Print the Area**: Use the `print()` function to display the calculated area.
*Detailed Steps:*
1. **Import Math Module**:
Use `import math` to import the `math` module, which provides access to the constant `pi`.
2. **Prompt User for Radius**:
Use the `input()` function to ask the user for the radius of the circle.
3. **Convert Input to Float**:
Use the `float()` function to convert the radius from a string to a floating-point number.
4. **Calculate Area**:
Use the formula `area = math.pi * radius ** 2` to calculate the area, where `math.pi` provides the value of π (pi).
5. **Print the Area**:
Use the `print()` function to display the calculated area of the circle.
