If the domain of the square root function f(x) is x<_7, which statement must be true? a) 7 is subtracted from the x term inside the radical.
b) the radical is multiplied by a negative number.
c) 7 is added to the radical term.
d) the x term inside the radical has a negative coefficient.

the line of

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
