What does this text mean "more '%' conversions than data arguments"

I dont understand what I am doing wrong in this segment.

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

As you code currently stands, you haven't told the printf statement what float value you want to replace the %f with. So I believe your output would be exactly "A ball with a radius of %f inches." For example if I wanted to print my age on the screen as a float, I would do:

float age = 18.0;
printf("My age is %f", age);

The extra part I've added there is what you're missing. This tells the printf statement that I would like to take whatever value is currently stored in the variable age, and substitute into my string where %f is, to be printed out.

Thank you I completely spaced that out.
