    Answer: 14 km

    Step-by-step explanation:

    To find out the radius of a circle we can use the formula of

    A=pi r^2

    Our area is 615.75 square kilometers:

    615.75=pi r^2

    divide by pi on both sides

    615.75/pi = r^2

    take square root of both sides

    r=sqrt615.75/pi

    r=13.999975

    Assuming it will be rounded to two decimal places the radius would be r=14.00 km
