  1. The area of the white circle: S₁ = π(1/2B)² = 3.14 × (14 × 1/2)² = 153.86 cm²
  2. The area of the big circle: S₂ = 1/2π(1/2A)² = 1/2 × 3.14 × (28 × 1/2)² = 307.72 cm²
  3. The area of the blue shaded figure:
  • S = S₂ - S₁ = 307.72 - 153.86 = 153.86  cm²

Answer: 153.86 cm²

Ok done. Thank to me :>
