Let the radius of each circle be 'r',

All circles are circumscribed by a square,

Area of square,

$= s^2$

$= (4r)^2$

$= 16r^2$

Now area of each circle,

$= \pi r^2$

So, the area of 4 circles

$= 4 \pi r^2$

Remaining area,

$= 16r^2 - 4 \pi r^2$

$= 4r^2(4 - \pi)$

It's given that radius of each circle is 1 cm,

Now sub,

$= 4(1)^2 (4 - \pi)$

$= 16 - 4 \pi$

Answer 2
