Kiyo used to wire fencing to form a border around a circular region in his backyard. 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 ?

Respuesta :

Answer:

The total length of the border is [tex]31.4\ yd[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

we have

[tex]r=5\ yd[/tex]

assume

[tex]\pi=3.14[/tex]

substitute

[tex]C=2(3.14)(5)=31.4\ yd[/tex]
