Question

The volume of the solid that results when y=6/7x^2 and y=13/7-x^2 is rotated around the x-axis.

Answer 1

okay i think this it:

\[\int\limits_{-1}^{1}\] (13/7 - x^2)^2 - (6/7 x^2)^2 dx

Answer 2

oh yeah then multiply by pi

Answer 3

didja get that :)

Answer 4

Thankssss

Answer 5

you should only do the righthalf tho; from 0 to 1 otherwise it might give you a zero

Answer 6

Actually, I had to find the points of intersection and that's what the integral had to be from and to.

Answer 7

Thanks, guys. I really appreciate it.
