Let y = 3x + 1, y = 0, x = 0, and x = 2. Find the volume of the region revolved about each of the lines below. Homework Help ✎
y = −1
is the incorrect set-up for a washer given.
Be sure to sketch the region before beginning.
If y = 3x + 1, then x = log3(y − 1).
Notice, both the outer and the inner radii are 1 unit longer than in part (a).
