Answer:
21.98cm²
Step-by-step explanation:
Area of the remaining part=Area of bigger circle−Area of the smaller circle.
Consider the bigger circle:Radius r=4cm
Area=πr²
=3.14×4 *4= 314/100*16 =5024 /100 =50.24cm ²
Consider the bigger circle:Radius r=3cm
Area=πr²
=3.14×3²
= 100
314 /100×9= 2826 /100 =28.26cm²
Area of the remaining part=Area of bigger circle−Area of the smaller circle.
=50.24cm² −28.26cm²
=21.98cm²
∴ Area of remaining sheet is 21.98cm²
