Extracted text: 1.Find the area of the surface. a. The part of the plane 2x + 5y + z = 10 that lies inside the cylinder x² + y? = 9 b. The part of the surface z = 1+ 3x + 2y² that lies above the triangle with %3D vertices (0,0), (0, 1), (2, 1) c. The part of the paraboloid z = 4 – x2 – y² that lies above the xy- plane d. The part of the sphere ² + y? + z² = 4 that lies within the cylinder x2 + y? = ax and above the xy, plane.
