Answer 3

if y = x^7
x = y^(1/7)

Answer 4

right so then what?

Answer 5

so you need to integrate that between y = 0 and y = 128

Answer 6

so int from 0 to 128 x=y^1/7 dy?

Answer 7

No Sorry I misread the question
You need the volume of revolution, not the area

so you need pi outside the integral and you also need to square y ^1/7
