Step-by-step explanation:

area of remaining part is 1 cm .....

Answer 2

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
