iOS development Variables Challenge help

So it tells me to create a float variable called radius that equals to 14.5, so i did and i passed.

float radius = 14.5;

Ok, so then it tells me to use a printf statement and use the variable in it.

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

I keep on failing it and i can't get pass this point, can someone tell me what i am doing wrong.

you need to close the quotes after the string, not after the variable name

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