The area of the shaded portion = 100.48 cm²
Solution:
Radius of the inner circle = 2 cm
Radius of the outer circle = 6 cm
Area of the inner circle =
Area of the inner circle = 12.56 cm²
Area of the outer circle =
Area of the outer circle = 113.04 cm²
Area of the shaded portion = Area of the outer circle – Area of the inner circle
= 113.04 cm² – 12.56 cm²
= 100.48 cm²
Hence the area of the shaded portion = 100.48 cm²
