Question 1:

\fFor each surface r (u, v), identify the best description of the surface's shape. T (u, V ) Shape V a. plane V b. screw V c. cone d. parabolic cylinder VFor each surface Tu, v), identify the shape of the grid curves when v is constant Some shapes may be used more than once. r (u, v ) Grid Curve V a. helixes b. circles c. lines V d. parabolas VFind the surface area of the part of the plane z = 5 + 2x + 7y that lies inside the cylinder 22 + 2 = 1
