A solid lies between planes perpendicular to the xaxis 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 = \".136 x2 to the semicircle 5r = -J 35 x2 _ Find the volume of the solid. 0 A, 144 O 3_ 51's 0 c. 1152 O D_ 288
