And then let's see, we could multiply both sides by negative one. So negative Y squared over 16 is equal to X minus nine. And now we could add nine to both sides and we get nine minus Y squared over 16 is equal to X. And so we could substitute that right over there. So another way to express the volume of this little slice right over here of infinitesimal depth, DY depth, is going to be Y times nine minus Y squared over 16 DY. Y squared over 16 DY. And if we want to find the volume of the whole figure, that's gonna look something like that, we're just going to integrate from Y equals zero to Y is equal to 12.
