A circle of radius 2 cm is cut out from a square piece of an aluminium sheet of side 6 cm. What is the area of the left over aluminium sheet ?
➣ Side of the Square Piece of an aluminium sheet = 6 cm
➣ A circle is cutted from the square piece of an aluminium sheet
➣ Radius of the Circle = 2 cm
➣ Area of the Left Over aluminium Sheet
➪ Area of Square = (side)²
⇒ Area of Square = (6)²
⇒Area of Square = 36 cm²
➦ Area of the Square Piece of an Aluminium sheet = 36 cm²
➦ Take value of π = 3.14
⇒ Area of Circle = 3.14 × 2 × 2
⇒ Area of Circle = 12.56 cm²
➪ Left over area of the Sheet = Area of Square- Area of Circle
⇒Left over area of the Circle= 36cm² - 12.56 cm²
⇒Left over area of the Circle = 23.44 cm²
➦ So, the area of the left over Aluminium sheet is 23.44 cm²
