The boundary of a wildlife refuge is located 6.2 miles away in all directions from the refuge headquarters. How many square miles are in the wildlife refuge?
NOTE: The refuge has a circular shape.
The area of the refuge is
square miles. (round to the nearest whole mile)

the radius is 2 times the diameter.

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
