Do you really mean y = 20 sqrt y?
That would mean y = 400
Isn't there an x upper limit?
Do you mean x=1?
You need to be more careful typing your questions
can you please help me, i'm really confused
Use the method of cylindrical shells to find the volume V of the solid obtained by rotating the region bounded by the given curves about the x-axis.
y= 20sqrt y, x=0, y=1
