graph the area bounded by y= x^2 +1 and y= -x +3

find the volume of the solid formed by revolving teh area bout the x-axis

h=____?

DISC or washer method?

find all the radiuses

use integration to find the volume...

i was trying this problem and.. i gotten

AREA= pi r ^2

v= intergral from a to b A dx

two intergrals.. 0 to -2.. and 0 to 1

PI( R^2 Outer - r^2 in)

i had some help from a friend but im still utterly confused and i have my finals tommorow...

i really need help from you guys.. thanks alot! willing to be pressing alot of thank buttons tonight ;P
