Asquare and a rectangle have the same perimeters. the length of a side of the
square is 4r - 1. the length of the rectangle is 2x + 1 and the width is x + 2.
write and solve an equation to find

20

step-by-step explanation:

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
