# core question watch

1. the diagram shows the curve with equation:
y=6/root x - 3.
The point P has coordinates (0, p). The shaded region is bounded by the curve and the lines x = 0, y = 0 and y = p. The shaded region is rotated completely about the y-axis to form a solid of volume V

(i) Show that V = 16π(1 - 27/(p+3)^3

i rearranged the y= into x= and squared it to get :
(6/(y+3))^4
then which limits do i put into get the equation in the question??^^
2. y=0 and y=p are the limits
