%f = Float Radius 14.5??? Or does it?

Hello there,

I am having issues with the challenge part 2 of 2. When it asks to write "A ball with the radius of 14.5 inches" I thought it wants you to write %f, to indicate the 14.5 from the float radius line/challenge before, but when I do that and check the work, it says that it does not work.

Is there something I am missing? I have tried everything else I could think of and nothing has worked so far.

Thank You!

You probably forgot to include the variable you wanted to use.

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

%f won't do anything if you forget to include the variable outside the string :) Hope that works!

Now it makes sense. I didn't really understand the purpose of the radius variable at the end until you showed me. Thank you!

Hey Zach, here's the answer.

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