Add a printf statement to print the radius variable. Here is what your output should look like: A ball with a radius of 14.5 inches.

Hi Bryan Deffinger

Thanks for posting! Could you add a link to the Code Challenge you're referring to, and add the code you're providing as an answer to this Forum post? That would be super helpful. If you're unsure how to add code or links we've provided a Markdown Cheatsheet, found below the new post or reply field, for your convenience. This post is also super helpful! Thank you so much for your help in troubleshooting this issue!

Hey Bryan, sorry for the delayed response here! You're pretty close, but let's step back and analyze what the challenge is asking for.

Here's our target: "A ball with a radius of 14.5 inches"

Just printing this would require:

printf("A ball with a radius of 14.5 inches");

But the printf function allows for substitution. We want to substitute the variable value for the number. Here's our goal

printf("A ball with a radius of <plug in the value of 'radius' here!> inches");

To do this substitution, we need to use a format specifier:

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

I don't want to give the whole answer away, so for the last part, we provide the value to substitute in by using the variable name. This is included as another parameter in the function, which we include by adding a comma after the statement and then typing the variable name. Review the video if you need to see the final format.

Hope this helps!

This is really new to me and I am a beginner..so the video seems to go really fast. I have watched it over and over again...thanks for all your help.
