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
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
