Will it be true to say that the perimeter of a square circumscribing a circle of radius $a \,cm$ is $8 a \, cm ?$ Give reasons for your answer.
Will it be true to say that the perimeter of a square circumscribing a circle of radius $a \,cm$ is $8 a \, cm ?$ Give reasons for your answer.
True Given, radius of circle, $r=a \,cm$
$\therefore$ Diameter of circle, $d=2 \times$ Radius $=2 a\, cm$
$\therefore \quad$ Side of a square $=$ Diameter of circle
$=2 a \,cm$
$\therefore$ Perimeter of a square $=4 \times( Side )=4 \times 2 a$
$=8 a\,cm$
