input: Write a function to prompt the user to enter the value of radius to calculate the area of a circle and print the result. The function should use a constant value of Pi (3.14) for the calculation.
  assert calculate_circle_area()=="The area of the circle is: 314.0"
output: def calculate_circle_area():
      radius = float(input("Enter the value of radius: "))
      area = 3.14 * radius * radius
      return f"The area of the circle is: {area}"
