# Create a float variable with the name 'radius' which has a value of 14.5

I am sure I am doing it write? Please advise, I thought the answer can be either of the following:

float 'radius'[0]; radius[0] = 14.5;

float radius[0] = {14.5};

The syntax you are using is for arrays. It looks like you're trying to create an array of size 0.

To create a float variable, you don't need the square brackets or the curly brackets, see below:

```float radius = 14.5;
```

Hi Kristen, thank you so much you are an angel!

The next part of the question says: 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.

So I put the answer as

printf("radius %f\n");

but then it says the output should look like, A ball with a radius of 14.5 inches

So then I thought the answer will be:

printf("radius %f\n", A ball with a radius of);

I am confused :(

Ahh!! I don't it yaaaay!!!

I wrote out printf("A ball with a radius of %f\n, radius);

and it worked..!!

Thanks a lot Kristen, you are a huge help!!

Glad you got it figured out :)
