p=4*side
=4*16.5
=66cm^2
p of square= circumference of circle
66=2*pie*r
r=21/2 cm
plzz mark it brainliest

THANKS FOR THE QUESTION !
_______________________________
GIVEN :
=> A WIRE IS BENT :
=> 1ST CONDITION :
=> IN A SQUARE SHAPE :
_______________________________
THE DIMENSION OF THE SQUARE SHAPE :
=> SIDE :
=> 16.5 CM
_______________________________
SO,
=> THE LENGTH OF THE WIRE :
=> PERIMETER OF THE SQUARE SHAPE
_______________________________
PERIMETER OF A SQUARE :
=> 4 * SIDE
=> 4 * 16.5
=> 66 CM
_______________________________
NOW,
=>[THE 2ND CONDITION :
=> THE WIRE IS STRAIGHTENED :
=> AND AGAIN BENT IN A CIRCULAR SHAPE :
______________________________
LENGTH OF WIRE :
=> CIRCUMFERENCE OF A CIRCLULAR SHAPED WIRE :
=> 66 CM
_______________________________
CIRCUMFERENCE OF A CIRCLE :
=> 2 * π * R
_______________________________
FROM THE INFO :
=> 2 * π * R = 66 CM
=> π * R = 66 / 2
=> 22 / 7 * R = 66 / 2
=> R = 66 * 7 / 2 * 22
=> R = 3 * 7 / 2
=> R = 21 / 2
=> R = 10.5 CM
______________________________
SO,
=> RADIUS :
=> ..................... 10.5 CM .....................
______________________________
HOPE IT WILL HELP U .......
THANKS AGAIN .........
