(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the area enclosed by the y axis, the line y = 3 and the curve x = y^2

2. Relevant equations

[/b]3. The attempt at a solution[/b]

Area = [tex]\int[/tex] 3 to 0 y^2.dy

= (1/3 y^3) 3 to 0

= (1/3 x 27)

= 9 sq units

Im not really confident on the y axis questions, can you please confirm my understanding. If this same area is then rotated 360 degrees about the y -axis, can I seek guidence on how to do this. Cheers P
