A circle of radius 2 cm is cut out from a square piece of an aluminum sheet of side 6 cm. What is the area of the left over aluminum sheet?

It is given in the question that,


Side of square = 6 cm


Area of square = (Side)2


Area of square shaped sheet = (6)2


= 36 cm2


It is also given in the question that,


Radius of circle = 2 cm


As we know that,


Area of the circle = πr2


Area = 3.14 × 2 × 2


= 3.14 × 4


= 12.56 cm2


Hence,


Remaining area of the sheet = 36 – 12.56


= 23.44 cm2
