Please help me answer the following. Thank you!

2. Given the functions flee) = 1+ TX + gla)=1, bounded by me 4, a ) find the volume of the solid when this is rotated about the x-aris . Sketch graph : R(x ) = r ( x) = set up integral : Solve : ( integrate by hand ) b ) Find the volume of the solid whose base is formed by f (x ) + glx) by using cross sections of squares perpendicular to the x-axis . ( reference the functions in part a ) . Integrate by hand
