Answer:

[tex]\pi[/tex] x miles

Step-by-step explanation:

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

r=radius = x/2

C= 2×[tex]\pi[/tex] × x/2

C=[tex]\pi[/tex] x

Answer:

πx miles

Step-by-step explanation:

Given in the question,

radius of a circle = x/2 miles

To find circumference of a circle we will use following formula

2π * r

where π is constant = 3.14

            r is radius of circle

Plug values in the formula

2(3.14)(x/2)

2 will cancel out

So we are left with 3.14x miles or πx miles
