What have you tried? How far have you gotten on this exercise? Please be complete. Thank you!
do i use the formula V=(2pie)interval from a to b ((f(x)-(g(x)))dx
If thats the right formula i get the answer to be 18pie/2

Ok i forgot that x in the beginning equation. So, with the problem y=(x^3)-(5x^2)+(6x), x=2, y=0 the answer for this one would be 24pie/5
