Find the volume using the shell method  about the xaxis
x=y^2/3

v = ∫2πrh dy
where r=y and h=x
v = 2π∫xy dy
Can't tell whether you mean (y^2)/3 or y^(2/3)
anyway, plug it in and use the appropriate limits.

It is y^(2/3)  we have not gone over shell method yet so.....

so, you have
v = 2π∫(y^(2/3))y dy
= 2π∫y^(5/3) dy
= 2π (3/7) y^(7/3)
but you need to specify the limits of integration, since the curve is openended.

The limits are 0,3
