Question

The region bounded above by the line, y = 6, below by the curve y=sqrt(x), and to the left by the y-axis. The solid is rotated along the following lines: C. The line y=6 D. The line x=36. These are two separate rotation axis and answers.

Answer 1

which method?

Answer 2

we need to know the point of intersection here

Answer 3

Hey sorry, keyboard died. The point of intersection is (4,16).

Answer 4

really? i see it as (6,36) meself

(y=6) = (y=sqrt(x))

6 = sqrt(x) at x=36
