Question:

The diagram shows part of the curve

and a point P(6, 5) lying on the curve. The line PQ intersects the x-axis at Q(8, 0).

i. Show that PQ is a normal to the curve.

ii. Find, showing all necessary working, the exact volume of revolution obtained when the shaded region is rotated through 360° about the x-axis.
