Question

Answer 1

The circumference of the cookie is 37.68 inches.

Explanation:

We have,

The area of a cookie is 113.04 square inches.

It is circular in shape. The area of circle is given by :

`A=\pi r^2`

r is radius of circle

`r=\sqrt{(A)/(\pi)} \\\\r=\sqrt{(113.04)/(3.14)} \\\\r=6\ \text{inch}`

The circumference of circular shaped object is given by :

`C=2\pi r\\\\C=2* 3.14* 6\\\\C=37.68\ \text{inch}`

So, the circumference of the cookie is 37.68 inches.
