i don't know why they couldnt've just shaded it. this is not fucking english,

i mean, why the fuck did you include a graph then?

am i right or ?

my idea is having a cylinder with height 3π and radius 1, getting its volume, then subtracting the volume made by rotating around y axis, x=0 -> x=1 and y=0 -> y=3π/2

i dont see how it could be wrong because the volumes should be equivalent but chatgpt says its so wrong it is 1am i guess i am tripping as heck

i think u are.

also the HSC always shows you a shaded graph for these types of questions.
