    Answer:

    Step-by-step explanation:

    The formula for determining the area of a circle is expressed as

    Area = πr²

    Where

    π is a constant whose value is 3.14

    r represents the radius of the circle.

    Considering the inner layer

    radius = 2 millimeters

    Area of base = 3.14 × 2² = 12.56 mm²

    Considering the outer layer,

    Radius = 6 mm

    Area of base = 3.14 × 6² = 113.04 mm²

    Percent of the area of the base of the outer layer that is the area of the base of the inner layer is

    12.56/113.04 × 100 = 11.1%
