%f entered incorrectly?

Hi this is silly since I'm only in Stage one, but I can't understand why this is incorrect when %f is to float and that is what I have entered.

variable_assignment.mm 
float radius = 14.5;
printf("A ball with a radius of %f inches");

Hi Lucy,

You have a few issues with your formatter which are as follows:

  1. The task requires you start the formatter with A, you have The
  2. You have /n at the end of your string, instead you should have a space and inches
  3. You're not passing the variable radius to your printf declaration
printf("A ball with a radius of %f inches", radius);

Happy coding.
