Thanks a lot) THat was such a small thing that I couldn't notice even. So means at the end of () you shouldn't be using any signs such as a comma or semicolon...

Your formula for the volume of a sphere is missing a multiplication sign

{ return (4/3) Math.PI * Math.pow(radius,3) ; }

should be

{ return (4/3)* Math.PI * Math.pow(radius,3) ; }

Thanks for the response. But i still don't understand why there's no output on console.log and just undefined Syntax Error(( <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Practice JavaScript Math</title> <link href="css/styles.css" rel="stylesheet">

</head> <body> <script src="Untitled-1.js"></script>
</body> </html> // Even the html is connected in the right way as i guess

im getting this same error too. Cant find the problem
