Area of the circle=πr×r
=3.14×2cm×2cm
=12.56cm^2
Area. of the square= s×s =6cm×6cm
36cm^2
Hence,the area of aluminium left over=
ar. of square-ar. of circle
=36cm^2-12.56cm^2
=23.44cm^2
=3.14×2cm×2cm
=12.56cm^2
Area. of the square= s×s =6cm×6cm
36cm^2
Hence,the area of aluminium left over=
ar. of square-ar. of circle
=36cm^2-12.56cm^2
=23.44cm^2

Hey mate ,here is your answer...
Given,
Radius of a circle=2cm.
Side of a square =6cm.
Area of a circle =πr^2.
=22/7×(2)^2.
=22/7×4.
=88/7.
Area of a square = (side)^2.
=(6)^2.
= 12cm^2.
area of aluminum sheet left = area of circle-area of square.
=(88/7)-(12)
=4/7cm^2.
=0.571428(approximately)...
I hope this may help you...
