Question

the perimeter of a circle and of a square are equal if the perimeter of them is 44 CM then the area of which one is Greater and how much

Answer 1

THANKS FOR THE QUESTION !

______________________________

GIVEN :

=> PERIMETER OF A CIRCLE = PERIMETER OF A SQUARE

_______________________________

PERIMETER GIVEN :

=> 44 CM

_______________________________

PERIMETER OF A CIRCLE :

=> 2 * π * R

=> 2 * 22 / 7 * R

=> 44 * R / 7

______________________________

BUT,

=> PERIMETER IS GIVEN :

=> 44 CM

_______________________________

RADIUS OF THE CIRCLE :

=> 44 CM = 44 * R / 7

=> R = 44 * 7 / 44 CM

=> R = 7 CM

________________________________

AREA OF THAT CIRCLE :

=> π * R^2

=> 22 / 7 * 7 CM * 7 CM

=> 22 * 7

=> 154 CM^2

_______________________________

PERIMETER OF A SQUARE :

=> 4 * SIDE

_______________________________

BUT PERIMETER IS GIVEN :

=> 44 CM

_______________________________

SIDE OF THE SQAURE :

=> 44 CM = 4 * SIDE

=> SIDE = 44 CM / 4

=> SIDE = 11 CM

_______________________________

AREA OF A SQAURE :

=> ( SIDE ) ^ 2

=> ( 11 ) ^ 2

=> 121 CM^2

_______________________________

AREA OF CIRCLE :

=> 154. CM ^ 2

AREA OF THE SQAURE :

=> 121 CM ^ 2

_______________________________

=> AREA OF A CIRCLE IS GREATER THAN THE AREA OF SQUARE

_______________________________

GREATER AREA OF CIRCLE :

=> AREA OF CIRCLE - AREA IF SQUARE

=> 154 CM ^ 2 - 121 CM ^ 2

=> 33 CM ^ 2

HOPE IT WILL HELP U ......

THANKS AGAIN .......
