Step-by-step explanation:
A circular sheet whose radius =4cm
and a circle of sheet whose radius =3cm
the area of the remaining sheet=(the area of circular sheet)-(the area of circle sheet)
the area of remaining sheet=(πr1^2)-(πr2^2)
=(22/7x16)-(22/7x9)
=(50.28-28.28)
=22.0cm^2
the area of sheet remaining is 22 cm^2
