Kiyo used wire fencing to form a border around a circular region in his back yard. If the radius of the circular region was 5 yards what was the total length of the border rounded to the nearest tenth of a yard?

To find the length of the border, you will need to find the circumference of the circular area that us formed.

C = pi x d (double the radius to find the diameter)
3.14 x 10 yards
C = 31.4 yards.

Kiyo will need approximately 31.4 yards of border.
