The circumference of a circle can be found using the formula:
C = 2πr
where C is the circumference and r is the radius.
Substituting the given value of radius, we get:
C = 2π(1)
C = 2π
Therefore, the circumference of the circle is 2π miles.
The radius of a circle is 1 mile. What is the circle's circumference?
