Q5 of 805 Page 1

The perimeter (in cm) of a square circumscribing a circle of radius a cm is


If square is circumscribing a circle. Then the diameter of the circle is equal to the length of the side of the square i.e.


Side of square = 2 × Radius


= 2a


⇒ Perimeter of square = 4 × Side


= 4 × 2a = 8a


Hence, Option A is correct.
