    Answer:

    44 square inches.

    Step-by-step explanation:

    radius of the base = 5.5 inches

    height of the cylinder = 4 inches

    The shape of the vertical cross section of the cylinder through the center of the base would give a rectangle with length of 2r, and its width is the height of the cylinder.

    Area of the vertical cross section = height x diameter

    diameter of the cylinder = 2r

                                            = 2 x 5.5

                                            = 11 inches

    The diameter of the cylinder is 11 inches.

    Area of the vertical cross section = 4 x 11

                                            = 44 square inches.

    The area of a vertical cross section of the cylinder through the center of the base is 44 square inches.
