Homework 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
