2. Given: region R below bounded by the graphs of y = vx - 3, y = 9 - r, and y = 0. (7.2) R (3,0) 19.0) (a) Find the area of R. (5 points) (b) SET UP a (sum of) definite integral(s) that is equal to the are length of the portion of the curve 7/ = va - 3 which serves as a boundary of R. (1.5 points) (c) Use the WASHER METHOD to set up (a sum of) definite integral(s) that is equal to the volume generated when R is revolved about the line r = 9. (2 points) (d) Set up a sum of definite integral(s) that is equal to the volume of the solid whose base is R and whose cross-sections perpendicular to the a-axis as equilateral triangles. (2.5 points)
