solid of revolution
Answered
I would like to first show the area under the graph of y=sqrt(x) between 1 and 4 (y>0), then show the solid of revolution about the xaxis, preferably using a slider for the angle of revolution. How might that be done?

Define a function f(x)= If(1 ≤ x ≤ 4, sqrt(x)) a slider 'angle'.
Then you show the solid of revolution with the command Surface(f, angle, xAxis)
You could show just the upper (positive) part while limiting the range of the slider

I use a trick to show the rotating trapezoid ;)
First, create the trapezoid, say trap:
where 1, 4 are the interval bounds, then I rotate it:and activate the trace for it.
