Radius of the circle= 2cm

Area of the circle to be cut out= \pi r^2πr

Answer:

given,

radius of circle =2 cm.

side of square =9 cm.

now,

area of square=side×side

=9×9

=81 cm^2

area of circle=πr^2

=3.14×2×2

=12.56 cm^2

area of left over sheet=area of square - area of circle.

=81 - 12.56

68.44 cm^2
