Question

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 ?

Answer 1

Answer:

The total length of the border is $31.4\ yd$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=5\ yd$

assume

$\pi=3.14$

substitute

$C=2(3.14)(5)=31.4\ yd$
