What is the surface area of design?

its c or d   take a lucky guess my dude

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

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
