Answer:
Area of shaded region = 351.68 cm²
Step-by-step explanation:
Area of a circle = πr²
where r = radius = 3.14
Area of bigger circle = 3.14 × 11²
= 3.14 × 11 × 11
= 379.94cm²
Area of smaller circle = 3.14 * 3²
= 3.14 × 3 × 3
= 28.26cm²
Area of shaded region = Area of bigger circle - Area of smaller circle
= (379.94 - 28.26) cm²
= 351.68 cm²
