The complete question in the attached figure
we know that
area of semi circle=pi*r²/2
diameter=5 ft
radius r=5/2----> 2.5 ft
so
area of semicircle=pi*2.5²/2-----> 9.8125 ft²
<span>the area of each stained glass section=area semicircle/3
</span><span>the area of each stained glass section=9.8125/3----> 3.27 ft</span>²---> 3 ft²
the answer is3 ft²

Answer: 1260</h3>
Work Shown:
We have 9 sides of this polygon. See the diagram below. So n = 9
Plug that into the formula below to find the sum of the interior angles
S = 180(n-2)
S = 180(9-2)
S = 180*7
S = 1260
Answer:
C. An increase of 20%
Step-by-step explanation:
50/100 = 60/x
Cross products
50
x = 6000
Divide 50 by both sides
x = 120
60 is 120% of 50, so there is a 20% increase
Hope this helps!
