Answer:
The circumference of the circle is 75.36 miles
Explanation:
Given
Radius, r = 12 miles.
Circumference is calculated using the following formula.
C = 2πr
take π as 3.14
substitute 12 for r in the formula above.
C = 2 * 3.14 * 12
C = 75.36 miles.
The circumference of the circle is 75.36 miles
