Let R be the region enclosed by the x-axis and the graphs of y=x4-2.3x³ +4 and the
horizontal line y=4 as shown in the figure above.
(a) Find the area of R.
(b) The base of a solid is region R. Each cross section of the solid perpendicular to the x-axis
is a semicircle whose diameter lies in the xy-plane. Write an expression involving one or
more integrals that gives the volume of the solid.
(c) The vertical line x-k divides region R into two equal areas. Write, but do not solve, an
equation involving one or more integrals in terms of k.
(d) Find the volume of the solid generated when R is revolved about the horizontal line y=-2.
