Well first lets correctly set up the printf statement. Let's create the variable and set up the printf statement.

float radius = 14.5;

You had forgotten to add the parantheses to printf statement and end with a semicolon now you need to add the text and identifier (which in this case is %f)

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

Now the last and final part of writing a printf statement is adding the variable(s) that the identifier is referring to.

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

That should be it! Hopefully that helped!
