Given that the central angle of a polygon is 18, then the number of sides of the polygon will be:
360/18
=20 sides
thus the side length will be:
144/20
=7.2 ft
hence the area will b given by:
p=s×n
a=s/[2tan(180)/n]
where:
Area=(a×p)/2
p=perimeter, s=side length, n=number of sides
p=7.2×20=144
a=7.2/[2tan (180/20)]=22.73
thus
A=(144×22.73)/2
A=1632.524 ft²
Answer:
23,128.56 qt
Step-by-step explanation:
We need to add the conversion from L to qt:
1 L = 0.26 gal = 0.26(4 qt) = 1.04 qt
Multiplying by 22239 L, we have ...
22,239 L = 23,128.56 qt
_____
<em>Comment on the answer</em>
The conversion factor given is good for 2 significant digits, so the answer would be appropriately rounded to 23,000 qt. The real conversion is to 23,496.519025 quarts when rounded to 6 decimal places.
