Treehouse TeacherHi there! I believe you've confused one of the comments shown in this video with the code. When writing out with paper and pencil we often denote a power with the ^ sign. But in the Math.pow function, we send in the first number and raise it to a power of another number. We do this by separating them with a comma.
Take a look again at 3:01 of the video.
If I simply replace the ^ with a , your code runs just fine!
Math.pow(radius,2)
Hope this helps!

Courses Plus Student 2,280 PointsYou are using the carrot sign. To use the Math.pow() method you send the base and the exponent separated by a comma (base, exponent).
function areacircle (radius){
return Math.PI * Math.pow(radius, 2);
}
console.log(areacircle(7.2));
Good luck Uche!
