Question

Find the volume of the solid generated by revolving the region bounded by y = x2, y = 0 and x = 1 about the line x = 2

Answer 1

see the drawing 2nd.
here Δx will be the width.
Δy will be the height.
and \[2\pi \times \Delta x\] will be the area covererd for volume.
now as per simple rule do lenght*breadth*height.
Put limits and integrate it.
