Answer:
50.2655
You see here, you find the diameter, which is 4, and multiply it. π
In conclusion, it is;
r = 2 m
V = 33.5103 m3
A = 50.2655 m2
C = 12.5664 m
The figures that can match are those which are similiar in shape.
Observe that polygons 1 and 4 have similar shape, hence those are the answer.
<h2>A is the answer.</h2>
1 hour each day is used for test
so 8-1=7 used per day
so commercial is 1 in the 4:2:1 so
4+2+1=7
ok, so 7 units, 7 hours
4 hour for private
2 hour for research
1 hour of commerical
4*5=20=private
2*15=30=research
1*4=40=commercial
20+30+40=90
percent from commercial
40/90=0.44444444444≈44.44% about 44%
12w - 27 = -34 + 14
w = 7/12
A -2w+21=-8w+36
w=17/8
B -5/6 w + 2 = -34+14w
w=216/89
C -47-10w=-9w-40-3w
w= 7/2
D 8/7w=13/14w+2
w=28/5
