Second: you're forgetting to state the variable you want to include in the printf.
printf("A ball with a radius of %f inches.\n", radius);
should work for you.

Courses Plus Student 141 PointsHow would you declare an integer variable named unstable and initialize it 25?
notf0und
11,940 PointsI haven't done any C or Obj-C in years, but I believe to declare such a variable, you'd do this:
int unstable = 25;

Courses Plus Student 141 Pointslast question bro (Use the compact form of division to divide unstable by 3)
notf0und
11,940 PointsI feel like I'm doing your work for you :P
unstable /= 3
If you Google "c compact form of division", a Treehouse forum link comes up as first result with the answer. I do suggest going back to the video before heading to Google or the forums, though :)
