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? (Take π = 3.14)

Solution:

Side of square piece of aluminum sheet = 6 cm

Radius of circle = 2 cm

Area of aluminium sheet left = Total area of square aluminium sheet – Area of circle

= Side × Side - πr²

= 6 cm × 6 cm - 3.14 × 2 cm × 2 cm

= 36 cm² - 12.56 cm²

= 23.44 cm²

Therefore, the area of the aluminum sheet left is 23.44 cm².
