to print a variable using a print f statement:

printf("here is a variable: %f in a printf statement", someVariable);

the challenge needs the string to be "A ball with a radius of 14.5 inches", but you need to replace 14.5 with a format specifier for floats which is %f.

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