Question

Find perimeter of the square, if radius of the circle is 3 cm.
cm

Answer 1

Given, the radius of the circle is 3 cm.
Diameter of the circle $=2\times \text{radius}$
$=2\times 3$ 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$\left(s\right)$ is 6 cm.
$\therefore$ The perimeter of the square $=4\times s=4\times 6\text{cm}=24\text{cm}$

Hence, the perimeter of the square is $24\text{cm}$.
