Is this wrong?

you forgot the second part of the print f statement which is the variable to be printed. A print f looks like this usually:

printf("something to print: %f", someVariable);

Even if it's one Variable you must always target it so always use the "," after your writing but before the parentheses and the semi-colon so like

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