    Answer: the area of the cylinder's base is ¼πx² square units.

    the height of the cylinder is 4x units.

    Step-by-step explanation:

    The The formula for determining the volume of a cylinder is expressed as

    Volume = πr²h

    Where

    r represents the radius of the cylinder.

    h represents the height of the cylinder.

    π is a constant

    From the information given,

    Volume = πx³ cubic units

    Base diameter = x units

    Radius = diameter/2 = x/2

    Therefore,

    Area of a circle = πr²

    Since the base is a circle, then

    Area of circular base = π * (x/2) ²

    = 1/4πx² square units

    Height = volume/πr²

    Since

    Volume = πx³

    Then

    Height = πx³ / (1/4πx²)

    = πx³ * 4/πx²

    = 4x units
