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

a. the line x = 1.

b. the line x = 2.

Step 1

a) Draw the situation first.

When it rotates around x=1 then the radius = 1-x

y=2x is given

So, x=y/2

Step 2

Use disk method to find the volume.

Step 3

b) Graph the situation using graphi...
