In questions 15-26: We are investigating the volume of the solid generated by rotating the shaded region about the indicated axes. Use the graph below: y 1 0 y = x y= Page 3 of 4. 1 X Section 6.2 (1 point each) - We are using the DISK/WASHER method for the questions in this section. For questions 15 and 16: Set up the definite integral that gives the volume. Your answer should be a definite integral with only one variable. DO NOT evaluate the integral. DO NOT simplify the integral. 15. Rotating about the x-axis. 16. Rotating about the y-axis. For questions 17-20: Determine the outer radius of the cross section (washer). 17. Rotating about the line y = 2. 19. Rotating about the line x = -2. 18. Rotating about the line y = 1. 20. Rotating about the line x = 1.
