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:
[tex]A = \pi * r ^ 2[/tex]
Where:
r: It is the radius of the circle
According to the data we have:
[tex]r = \frac {2} {2} = 1 \ in[/tex]
Thus, the area of the cookie is:
[tex]A = \pi * (1) ^ 1[/tex]
We have [tex]\pi = 3.14[/tex]
[tex]A = 3.14 * 1\\A = 3.14[/tex]
We round:
[tex]A = 3.1[/tex]
Thus, the area of the cookie is [tex]3.1 \ in ^ 2[/tex]
Answer:
[tex]3.1 \ in ^ 2[/tex]
