In 1988, the population of a city was 100,000. Then each year for the next five years, the population increased by 3%

i think this could be a possible answer (1 / 84) -1

good luck! : d

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

so mark-up is 0.4 multiplied by 180 = 72

i think this is a open ended question but i agree with other guy who said you should ask it at english section
