Sam used wire fencing to form a border around a circular region in his back yard. If the diameter of the circular region was 16 yards, what was the total length of the border, rounded to the nearest tenth of a yard?

The total length of the border = 50.2 yards

Step-by-step explanation:

Step 1 :

Given,

Diameter of the circular region = 16 yards

We need to compute the total length of the border.

Step 2 :

The total length of the border can be obtained by computing  circumference of the region with the given diameter

Circumference = 2(pi)(r)

where r is the radius

here diameter = 16, so radius = 8 yards

Hence circumference  = 2 (3.14) 8 = 50.24 yards

Step 3 :    

Answer :

The total length of given border = 50.2 yards (rounded off to nearest 10th)  

which expression represents the approximate length of bc?
