The measure of one side of a square is x+5. which expression represent the area and perimeter of the square? 2
A: X. + 5and4(x+5)

B: 2(x+5).and 4(x+5)
2
C: (X+5) and 4x+5
2
D: (x+5) and 4(x+5)

the answer is d

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
