Question

kiyo used wire fencing to form a border around a circular region in his backyard if radius of the circular religion was 5 yards what was the total length of the border rounded to the nearest tenth of a yard

Answer 1

The formula for circumference is πd. 
Diameter is 2r. 
5 x 2 = 10 
Use 3.14 for π. 
10 x 3.14 = 31.4 yards 

Hope this helps!

Answer 2

Answer:

31.4 yards.

Step-by-step explanation:

We have been given that Kiyo used wire fencing to form a border around a circular region in his backyard. The radius of the circular religion was 5 yards.

To find the total length of the border we will use circumference of circle formula.

$\text{Circumference of circle}=2\pi r$, where r represents radius of circle.

Upon substituting $r=5$ and $\pi=3.14$ in above formula we will get,

$\text{The total length of the border}=2*3.14*5\text{ yards}$

$\text{The total length of the border}=31.4\text{ yards}$

Therefore, the total length of the border is 31.4 yards.
