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%
