I don't know if this is the answer that you are looking for, but would the answer be all solutions?
Answer:
C = 14pi
Step-by-step explanation:
C = pi d
The radius is 7 so the diameter is
d = 2r
d = 2*7
=14
C = pi *14
C = 14pi
V=area of base times height
height=height
area of base=area of circle=pir^2
V=hpir^2
r=6
h=14
V=14pi6^2
V=14pi36
V=504pi
aprox pi=3.141592
V=1583.3 round
V=1583 cm^3
1/2 of 1/2 of 1/2 = 1/8.
There are 640 acres in a section, so 1/8 section = 80 acres.
_____
In surveying terms, "SW 1/2 of a section" is not a realistic specification of a piece of property.
Answer:
$ (7x+12)
Step-by-step explanation:
We have that,
Price of each cell phone plan = $x
Since, 3 friends pay extra $4 for the plan.
Thus, the amount paid by the three friends is $ 3(x+4).
Now, as the ramaining people do not pay the extra cost and there are 7-3 = 4 people remaining.
Thus, the amount paid by remaining people = $ 4x
Thus, the total cost of the plan will be $ [3(x+4) + 4x] = $ (7x+12).
Hence, the expression for the total cost of the seven plans is $ (7x+12).
