Answer:
21.98cm²
Step-by-step explanation:
Area of circle with radius 4cm
πr²=3.14*4*4=50.24cm²
now
area of removed circle with radius 3 cm
=πr²=3.14*3*3=28.26 cm²
AREA OF REMAINING SHEET
=(50.24-28.26)=21.98 cm²

Answer
the area of the circular sheet with 4 cm radius is ,
A = πr^2
= 16 π
The area of the circular sheet with 3 cm radius is ,
A = πr^2
= 9π
Since ,
The circle with radius 3 cm is removed , then the remaining area is ,
A = 16π - 9π
= 7π
= 7 * 3.14
= 21.98 cm^2
