Parker is placing square desks in rows of fours. The area of one row of desk is 36 square feet. What is the length of one row of desk ?

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

answer is b

tip: look up videos or do research on a question

hoped this !

to solve for a variable means to isolate the variable on one side of the equation.

note: we can write (1/2)(bh) as one fraction like this (bh/2). they mean the same thing.

we now have this:

a = (bh/2)

we multiply both sides of the fractional equation by 2. this is done to remove the fraction.

doing this we now have a linear equation:

2a = bh

we now divide both sides of the equation by h to find the value of b.

final answer:

(2a/h) = b
