7. The vertical line segment from the point (5,0) to (5,10) is revolved about the y-axis. (14 points) (a) What is the equation of the vertical line of interest? (b) Find the surface area of the surface of revolution. Draw and label a diagram as needed for surface area, then set up the integral and solve. (c) What is the volume enclosed by the surface of revolution created in Part (b)? Draw a diagram and label either the radii or the height and radius. Then, set up the integral and solve. You must use integration for credit
