Ninety percent of the schools students, or 540 students, attended a school assembly. how many students are there at the school? show work

Let x represent the number of students at the school

90% of x is 540

.90x = 540

x = 600 divided both sides by .90

600 students

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
