Good evening,

can you help me with those questions

1.

x Find the area of the surface generated by revolving the curve y = 12' - 1/3 Sx50, about the x-axis. . . . The area of the surface is . (Type an exact answer, using n as needed.)The area of the generated surface is D square units. (Type an exact answer, using 7: as needed.) Find the area of the surface generated by revolving x = 41/1 -y , 0sys about the y-axis. 16 3, 76 x=41 1 -y 4 The area is (Simplify your answer. Type an exact answer, using it as needed.)S = 21 V6x + 10 dx O 3 N/ W 21t (6x + 10) lo Evaluate the surface area. 3 N/ W S = 21 (6x + 10) 0 N / W N/W 9 28 10 N/ W N/ W Thus, the surface area is (28 9 10 square units.Find the area of the surface generated by revolving x = 2116-y, 0sys 15 about the y-axis . . .
