        Enter the real number as the radius R of a circle. calcule circumference and the area of that circle with the precision of 2 digits after the decimal point, in case R <0, print " NO CIRCLE ”.
Input:
A line of a real number R
Output:
Either 1 result "NO CIRCLE" or two lines corresponding to the circumference, the area of the circle is rounded to 2 digits after the decimal point.
Example 1:
Input:
