A solid lies between planes perpendicutar to the xaxis at x = B and x = 6. The crosssections perpendicular to the xaxis between these planes are squares whose bases run from the semiciche y = - 1' 35 x2 to the semicircle 5r = 1' 35 - x2 _ Find the volume of the solid. The volume of the solid '5 :l cubic units. (Simplify your answer.)
