Consider the function y = 4x + 5 between the limits of z = 1 and 2 = 5. a) Find the arclength L of this curve: L= Round your answer to 3 significant figures. b) Find the area of the surface of revolution, A, that is obtained when the curve is rotated by 2 radians about the a-axis. Do not include the surface areas of the disks that are formed at z = 1 and a = 5. A Round your answer to 3 significant figures.
