For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:

$A = \pi * r ^ 2$

Where:

r: It is the radius of the circle

According to the data we have:

$r = \frac {2} {2} = 1 \ in$

Thus, the area of the cookie is:

$A = \pi * (1) ^ 1$

We have
$\pi = 3.14$

$A = 3.14 * 1\\A = 3.14$

We round:

A = 3.1

Thus, the area of the cookie is
$3.1 \ in ^ 2$

Answer:

$3.1 \ in ^ 2$
