1. Find the radius of convergence of the power series Soo (3x) n Ln=0 n 2. The region bounded by the graphs of y = x'- 4x2+ 3x, y=0. Then find the area of the region from x=0 to x=3. 12 X -23. Use the shell method to set up and evaluate the integral that gives the volume of the solid generated by revolving the plane region of y = x2, x = 1, y = 0 about the x-axis
