Answer:

C≈18.85mi

Step-by-step explanation:

E.G :   to solve the equation for the diameter of the circle, d= C/π. In this example, "d = 12 / 3.14." or "The diameter is equal to twelve divided by 3.14." Divide the circumference by pi to get the answer. In this case, the diameter would be 3.82 inches.

circumference formula for circle: 2πr

diameter/2=radius, so the radius for this problem is 3 miles

C=2πr

 =2(3)π

 =6π
