Perl Programming CSC 2215 Section Name: Date: Assignment 1 (100 pts) Instructions: Complete the following exercises. You must submit cach script separately on D2L Dropbox. CHECK CALENDAR FOR DUE DATE 1. Write a program that computes the circumference of a circle with a radius of 12.5. Circumference is 2n times the radius (approximately 2 times 3.141592654). The answer you get should be about 78.5. 2. Modify the program from the previous exercise to prompt for and accept a radius from the person running the program. So, if the user enters 12.5 for the radius, she should get the same number as in the previous exercise . 3. Modify the program from the previous exercise so that, if the user enters a number less than zero, the reported circumference will be zero, rather than negative. 4. Write a program that prompts for and reads two numbers (on separate lines of input) and prints out the product of the two numbers multiplied together. 5. Write a program that prompts for and reads a string and a number (on separate lines of input) and prints out the string the number of times indicated by the number on separate lines (Hint: use the operator.) If the user enters "fred" and "3", the output should be three lines, cach saying "fred". If the user enters "fred" and **299792", there may be a lot of output
