import math

# Prompts the user for the radius
radius = float(input("Enter the radius of the circle: "))

# Calculates circumference and area
circumference = 2 * math.pi * radius
area = math.pi * math.pow(radius, 2)

# Prints the results
print(f"Circumference: {circumference:.2f}")
print(f"Area: {area:.2f}")

import math

# Calculates and prints the result
result = math.sqrt(49) + math.factorial(3)
print("Result:", result)
