Solution

Given, the radius of the circle is 3 cm.
Diameter of the circle =2×radius
=2×3 cm
=6 cm

When a circle is inscribed in a square, the diameter of the circle is equal to the side length of the square.

So, the side length of the square(s) is 6 cm.
The perimeter of the square =4×s=4×6 cm=24 cm

Hence, the perimeter of the square is 24 cm.
