python: Write a program that will find the area and perimeter of a circle with a radius given by the user.   Create two functions to do the calculations. The function to compute the area should return 3.14*radius**2. The function to compute the perimeter should return 2*3.14*radius.   Include a try/except to ensure that the user is entering a numeric value.
