13. Find the circumference of a circle with an

area of 6761 square millimeters.

291.4 millimeters

Step-by-step explanation:

The area for a circle is πr∧2

To solve for r you must do 6761 divided by π and then take the square root of that number. This gives you 46.39 which is the radius

The formula for the circumference of a circle is 2πr, so all you have to do is multiple 46.39 times 2π to get your answer.
