Hey Kurosaki! The x is also under the square root :smile: I actually added a new photo with a clearer equation if you wouldn't mind checking it out. ty

No problem! It's actually still 3u haha and it's called 'Applications of Integration' :party:

This is a clearer photo! Also, it is an area question so I had to multiply it by pi and square y, and kurosaki, the square root is over 2x. Thanks guys!
