Good evening,

can you help me with those questions. Please please send me the correct answers this is my third time asking to tutor

Use the shell method to find the volumes of the solids generated by revolving the shaded region about the indicated axes. Ay 4 X = 48 (y2 - y3 ) a. The x-axis b. The line y = 1 c. The line y = d. The line y = - UI N a. The volume is (Type an exact answer in terms of .)Find the volumes of the solids generated by revolving the triangle with vertices (2,2), (2,8), and (6,8) about (a) the x-axis, (b) the y-axis, (c) the line x = 7, and (d) the line y = 2. a. The volume of the solid generated by revolving about the x-axis is |cubic units. (Type an exact answer, using it as needed, or round to the nearest tenth.)The graph of the equation x2+ 2/ =42/ is one of a family of curves called astroids because of their starlike appearance (as shown in the accompanying figure). Find the length of this particular astroid by finding the length of half the first-quadrant portion, y = (42/3 -x2) , 2 5x54, and multiplying by 8. . . . The length of the given astroid is (Simplify your answer. Type an exact answer, using radicals as needed.)
