8-111.

Uh-oh! Arlen needs your help. He is trying to write an integral for the volume of square cross-sections perpendicular to the *-*axis where the base is the region bounded by the

*axis and* -

*over the interval*

These cross-sections are squares. This area formula is well known.

The function and the bounds must be in terms of , because the cross-sections are perpendicular to the

*-axis.*

Rewrite the function in terms of

*and determine the*

*-values that correspond with the given domain.*
