If an elevator goes 15 feet above ground in a building, it is said to be at +15 feet. if it moved to 3 feet below the ground, it is said to be -3 feet. what is the meaning of zero, positive feet, and negative feet?

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
