Answer:

5.495 inches.

Step-by-step explanation:

We have been given that Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. We are asked to find the circumference of an Oreo.

We know that circumference of circle is equal to $2\pi r$ , where r represents radius of circle.

We also know that diameter is 2 times radius.

$D=2r$

Upon substituting $2r=\text{ 1.75 in}$ , we will get:

$\text{The circumference of an Oreo}=\text{ 1.75 in}\times \pi$

Using 3.14 as an estimation for π, we will get:

$\text{The circumference of an Oreo}=\text{ 1.75 in}\times 3.14$

$\text{The circumference of an Oreo}=5.495\text{ in}$

Therefore, the circumference of an Oreo would be 5.495 inches.
