Radius Float variable?

In the first challenge it asks to create a float variable radius with the amount 14.5.

This is what I've submitted:

{ float radius = 14.5;


I'm pretty sure this is how you declare a float variable, but It's telling me to recheck my work. What am I doing wrong?

You don't actually need the curly braces when creating a variable.

Curly braces are used to denote a code block and you'll use them when you write functions, loops, conditionals, etc...

I'm having problem with this course as well. I keep thinking it's missing a video.

Hmmm. So I tried it again and it submitted this time. Not sure what I could have done differently but for anyone else having this problem - make sure you're writing on the first line. This is what I submitted as my code -

float radius = 14.5;

Good luck!

I'm confused now. Did you submit it the first time with the curly braces or without?

Jason Anello - Without the curly brackets the first time, hence my confusion as to why it wasn't running. I added the brackets in there for the post thinking that's what I was missing.

That's strange then because I don't see a difference between the two variable declarations.

I'm not sure if you're saying you put in the curly braces to post it as code but you need to use 3 backticks if you wanted to post it as code.
