Hi Paul,

This could have been the title for a css problem :)

In your printf call you are only passing in that string as an argument. However, it contains a %f format specifier meaning that it's expecting you to pass in a second argument of type float to replace that %f

printf ("A ball with a radius of %f inches.", radius);

The radius variable is passed in as the second argument to printf and it will replace the %f with the value of that variable.
