)) The model shows a quotient of 484.
<>) The model shows a dividend of 1,443.
()) 240 = 3 is not equal to 80.

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

b

step-by-step explanation:

this is because the profit is decreasing and turning into debt

pi or 3.14159265359 is an irratinal decimal
