Question

A circle of radius 1cm is cut out from a square piece of an Aluminum sheet of side 5cm.
(π = 3.14)

1 ) what is the area of the Aluminum sheet

2 )what is the area of the circle

Answer 1

$\Large{\red{\underline{\underline{\tt{AnSweR:}}}}}$

Area of the square is 6*6 = 36 cm²

Area of the circle is 3.14*2*2 = 12.56²

Hence remaining area is 36-12.56 = 23.44cm²

Answer 2

Step-by-step explanation:

The area of the square piece of sheet =(side)

2

=6

2

cm

2

=36 cm

2

The area of the cutter out circle =πr

2

cm

2

=π×2

2

cm

∴ leftover aluminum sheet area=36−3.14×4

∴ leftover aluminum sheet area=23.44 cm
