Find the coordinates of the intersection points A and B. b) [1.5 point] Set up a definite integral that calculates the length of the portion of the curve C that lies under the line C. Do not evaluate the definite integral. c) [3.5 points] The rotation of the portion of the curve C that lies under the line C about the x-axis generates a solid of revolution. Set up a definite integral that calculates the surface area of that solid of revolution. Do not evaluate the definite integral. Given the curves C1: y = x2 + 3 - 4 and Cr:y = x 1.
