The graph of a function is shown: Which of the following correctly identifies the set of outputs?
[5.-2), (1, -1). (-2, 2), (2,5)}
-2,5). (-1, 1), (2.-2), (5,2))
(-2-1, 2,5)
(-2, 1, 2,5)

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
