Step-by-step explanation:
Radius of biggest circle = 8cm + 4cm = 12cm
so, Area of biggest circle = πr^2 = 3.14 × 12×12 = 452.16.
Radius of middle circle = 8cm
so, Area of this circle = 3.14 × 8×8 = 200.96.
Radius of smallest circle = 4cm
so, Area of circle = 3.14 × 4×4 = 50.24.
Therefore, Area of shaded region = 452.16 - 200.96 - 50.24 = 200.96.
