input: Write a function to prompt the user to enter the value of radius to calculate the area of a circle. The function should use the value of Pi as 3.14, calculate the area, and print the result.
  
  assert calculate_circle_area()
  
  Note: This function should prompt the user for input and print the output accordingly. There is no direct return value from this function since the output is printed.
output: def calculate_circle_area():
      radius = float(input("Enter the value of radius: "))
      area = 3.14 * radius * radius
      print("The area of the circle is:", area)
