Answer:

10.4 yd

Step-by-step explanation:

Circumference of a circle is the measure of the perimeter of a circle.  In this case, the border is around a circular region with a radius of 5 yards.  The general formula for the circumference of a circle:

C = 2πr, where 'r' is equal to the radius

Since the region has a radius of 5 yards, we can find the total length of the border needed:

C = 2π5 = 10π or 10(3.14) = 31.4 yards
