The shaded region is bounded by the curve and the lines \(x = \frac { 1 } { 6 } \pi\) and \(y = 0\).
  1. Use the trapezium rule with two intervals to find an approximation to the area of the shaded region, giving your answer correct to 3 significant figures.
  2. Find the exact volume of the solid formed when the shaded region is rotated completely about the \(x\)-axis.
