The sheets of metal being used to create the drain are 8.5 feet wide. The engineer wants to identify possible heights and bottom width
measurements she could use to construct the drains.
1. Determine the bottom width for each given height. Then,
define a function w(h) for the bottom width given a height
of h feet.
HELP PLSS!!

i have not got your picture clearly so see it once again

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
