Multiple Choice

Find the volume of the described solid.
-The solid lies between planes perpendicular to the $x$ -axis at $x = - 6$ and $x = 6$ . The cross sections perpendicular to the $x$ -axis between these planes are squares whose bases run from the semicircle $y = - \sqrt { 36 - x ^ { 2 } }$ to the semicircle $y = \sqrt { 36 - x ^ { 2 } }$ .
