**Damon**, Sunday, January 31, 2010 at 6:13pmintegral from y = 0 to y = 16 (origin to x = 2)

find volume of outer cylinder of radius 16

Vol - pi r^2 h = pi (16^2) (2)

find volume generated by inner curve between x axis and y = 4 x^2

Vinner = pi y^2 dx from 0 to 2

= pi 16 * integral x^4 dx

= 16 pi (32/5)

then subtract the inner from the outer

2 pi (16^2) - 16 pi (32/5)

= 32 pi *16 - 32 pi *16/5

= 32 pi (4/5) (16)
