    radius is 7 cm

    Step-by-step explanation:

    The volume of a cylinder is given by

    V = pi r^2 h

    We know the volume is 1323 pi and the height is 27

    1323 pi = pi r^2 * 27

    Divide each side by 27 pi

    1323 pi / 27pi = pi r^2 * 27 / 27 pi

    49 = r^2

    Take the square root of each side

    sqrt (49) = sqrt (r^2)

    7 = r
