Solve the following from a to d:

Given: region R below bounded by the graphs of y = √√x − 3, y = 9 — x, and y = 0.
-
(7,2)
R
(3,0)
(9,0)
(a) Find the area of R.
(b) SET UP a (sum of) definite integral(s) that is equal to the arc length of the portion of the curve
y = √√√x - 3 which serves as a boundary of R.
(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 x = 9.
(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 x-axis as equilateral triangles.
