Given the curves a) [4 points] 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 01 that lies under the line 02. Do not evaluate the definite integral. c) [3.5 points] The rotation of the portion of the curve Cl that lies under the line 02 about the maxis 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. 'l'3.___ I_.I:J_ an.n.nn
