Hey Yoel,

So in order to create a variable we have to declare what type of variable we want. So the first thing we'll type out is float.

Then we give our variable a name. In the case of this code challenge, the name it wants us to give is "radius." So let's add that to the code, and now we have float radius.

Finally, we have to give our float variable a value. The challenge wants us to give the value of "14.5." So we say that we want our float variable named radius to equal 14.5, and we end up with this:

float radius = 14.5

I hope that clears some things up for you!
