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
