You would make a table first, the top part, just start from zero and add every time. Hope this helps
The answer is 1808.64 ft²
To calculate area of square we need to find radius r. Radius is a half of a diameter:
r = d/2
The blueprint:
d = 18 cm
r = 18/2 = 9 cm
<span>The blueprint has a scale of three centimeters to four feet. Actual radius r1 is:
</span>3 cm : 4 ft = 18 cm : r1
After crossing the products:
r1 = 4 ft * 18 cm : 3 cm
r1 = 24 ft
The area of the circular base of the fountain is:
A = r1² * π
π = 3.14
r1 = 24 ft
A = 24² * 3.14
A = 1808.64 ft²
To solve this problem you must apply the proccedure shown below:
If 
, you have that:
Because 
and 
Therefore, as you can see, the answer is: 
That would be : 3:5 = 12:20....because 3/5 = 12/20
Answer:
(-a)n is negative number, and since you did not provide a clear first option, I will assume the answer is none of the above. However, the accurate answer is C
