the red color is me trying to reflect it across the x=6 im not really sure what im doing

#

i know for disk its outside radius minus inner radius so i thought it was (6)-(6-y) but idk i just confsued myself

hazy compass this is right do you understand why?

well when i plug it into the calculator it doesnt give me the answer thats correct 😭

#

i thought it was 6 the line subtracted from the area beneath the curve which was 6-y

#

but it apparently isnt 😭 i had it bounded in the limnits of 0-4
