Question

A circle of radius 2 cm is cut out from a square piece of aluminum sheet of side 6 cm. What is the area of the left over aluminum sheet ,take pie as 3.14​

Answer 1

$\textbf{\underline{\underline{According\:to\:the\:Question}}}$

${\boxed{\sf\:{Radius\;of\;Circle}}}$

= 2 cm

${\boxed{\sf\:{Side\;of\;Square}}}$

= 6 cm

Using formula :-

Area of square = Side²

                    

= 6²

                    

= 36 cm²

We know that :-

Area of  the circle = πr²

${\boxed{\sf\:{Here\;we\;substitute\; \pi = 3.14}}}$

                        

= 3.14(2)²

                         

= 3.14(4)

                          

= 12.56 cm²

${\boxed{\sf\:{Area\;left}}}$

= Area of square - Area of circle

                                        

= 36 - 12.56

                                        

= 23.44 cm²

Hence :-

${\boxed{\sf\:{Area\;left\;is\;23.44 cm^{2}}}}$

${\textbf{Answer}}$

SIDE OF A SQUARE = 6 CM

RADIUS OF CIRCLE = 2 CM

AREA= SIDE X SIDE = 6 X 6 = 36

Or

Area of square-shaped sheet = (Side)2= (6)2= 36 cm2

Area of circle = 3.14 × 2 × 2 = 12.56 cm2

Remaining area of sheet = 36 12.56 = 23.44 cm2

Or

AREA OF LEFT OVER SQUARE = 36 - 12.56 = 23.44

ANS = 23.44cm^2
