Respuesta :

Circumference = 3.14 * diameter

Diameter = 2 *  radius

To find the radius, we can use this equations, but backwards.

First, let's convert the circumference to the diameter.

13 / 3.14 = 4.14

Now, let's divide this by 2 to find the radius.

4.14 / 2 = 2.07

The radius of a circle with a circumference of 13 feet is 2 feet.
