The shaded region is bounded by the curve, the \(x\)-axis and the line \(x = 3\).
  1. Use Simpson's rule with six strips to estimate the area of the shaded region. The shaded region is rotated through four right angles about the \(x\)-axis.
  2. Show that the volume of the solid formed is \(\pi ( 3 - \ln 4 )\).
