Use the method of cylindrical shells to find the volumeVgenerated by rotating the region bounded by the given curves about the specified axis.

y=x^(1/3),y= 0,x=1;aboutx=4

I used the limits 0 to 1 and I did the integral of (x+4)(x^1/3). I got 48/7 pi but this is the wrong answer. I don't know what I'm doing wrong
