Answer:
18.84 miles.
Step-by-step explanation:
We want to find the circumference of a circle given that we know its radius.
The answer is: 18.84 miles.
Let's see how to compute the circumference.
For a circle of radius R, the circumference is given by the formula:
C = 2*pi*R
Where pi = 3.14
Then if the radius of the circle is equal to 3 miles, we can see that the circumference is given by:
C = 2*3.14*(3 miles) = 18.84 miles.
The circumference of the circle is 18.84 miles.
