ok the challenge wants to you print that string using the value of your float radius variable, not a static 14.5 like you have right now. Remember that you can use print f to print the value of variables like so:

printf("The road was %d miles long", roadLength);

and the value of my roadLength variable will be inserted into the string where the format specifier is. so if the value of that variable was 10 the statement would output "The road was 10 miles long". The same principle can be applied to your challenge. except instead of using %d (which is for printing ints) you need to use %f (for printing floats)

can you post your code? the format specifier for floats is %f so thats what you should be using
