Question

i can't figure out this problem for the life of me. it's let the region be bounded by y=x^2, x=1, and y=0. find the volume of the region about the line y=-1

Answer 1

Volume, or area?

Answer 2

volume

Answer 3

:( I can't figure it out either

Answer 4

is anything unclear

Answer 5

are you rotating it?

Answer 6

Yeah if it's a rotation about y = -1 then it's doable

Answer 7

yes you have to rotate the region bounded by the equations around the line y=-1

Answer 8

Why didn't you say so! :-P

Answer 9

it made sense to me, sorry

Answer 11

that's what i thought too but the program i'm using wants it in terms of y so y=x^2 should be x=sqrt(y) so then the graph should look like this.....
