a circle of radius 2 cm is cut out from a square piece of a sheet of side 9 cm what is the area of the left over sheet ?{π =3.14
Answers
Answer:
:
Side of the square sheet= 6m
Area of the sheet= \left(Side\right)^2=\left(6\right)^2=36\ cm^2(Side)

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
