Extracted text: where R is the region in the upper half-plane bounded by the circles x2+y2 = 4 and x²+y² = 9. #2. Use polar coordinates to find the volume of the solid bounded by the plane z = 0 and the paraboloid 2x² + 2y² +z = 8. #3 Sketch the region R inside the curve r = 1+ cos A and outside the circle r = 1 and use
