Thread: work with conical tank

A tank with a radius of 1 at (0,4) is filled with the 3-meter mark.
how much work is done (1,000kg/m3 9.8m/s2)

I got the integral from 0 to 3


with the radius of x which is x=y/4
1000x9.8pi [integal0->3](y^2/16)(4-y)dy

but I'm not getting the right answer, what am I doing wrong?
Thanks.
