1. Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified lines.

y = 4 – ½x, y = 0, x = 0, x = 1; about the x-axis

2. Find the volume V of the solid obtained by rotating the region bounded by the given curves about the x-axis.

y = 2-2x^2, y = 0

3. Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line.

x = 2 sqrt(3y), x = 0; y = 9; about the y-axis

Sketch the region.

Sketch the solid and a typical disk or washer.
