Remember that the formual for the area of a circle is:

$A=\pi r^2$

And the formula for the circumference is:

$C=2\pi r$

Using this formulas and the data given,

$\begin{gathered} A=\pi(5^2)\Rightarrow A=78.54 \\ C=2\pi(5)\Rightarrow A=31.42 \end{gathered}$

The cookie has an area of 78.54 square inches and a circumference of 31.42 inches
