simple program help required
The circumfrence of a circle is
#!/usr/bin/perl
print 2 * 3.141592654 * 12.50 \n"; # pi= 3.141592654
# r= 12.50

I need a simple program showing me all the steps..to modify the above to prompt for and accept a radius from the person running the program. So if the person enters 12.5 for the radius,we get the circumference . # 78.5
thanks
