Volume of a cylinder= π r² h
Diameter(D)= 2r
D= 225h
D= 225(2214)= 498150 ft
498150/2=r
r= 249075 ft
h= 2214 ft

V= π (249075²)(2214)
V= π(62038355625)(2214)
V ≈ 4.32*10^(14) ft³

Answer:
The volume is about 4.32*10^(14) cubic feet.

(If I got the numbers wrong for the height or diameter please let me know and I'll fix it later today because this answer seems really large and your numbers are written weird in your question. I attached an image of how your question appeared to me)

The answer would be x ≠ 0

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First start with the left side, doing distributive property

So... -2(x) = -2x and -2(5) = -10 Therefore on the left side you now have -2x -10

Next do the same on the right side

-2(x) = - 2x and -2(-2) = 4 so you have -2x + 4 + 5 and you add 4 and 5, leaving you with -2x + 9

Now that you have simplified both sides the problem now looks like this:

-2x - 10 = -2x + 9

Because you have equal terms on both sides (-2) those cancel out so you have -10 = 9

Just from looking at this we know that the statement is false because -1o does not equal 9

*The symbol, "≠" means not equal to"

serg [7]

Think of when If you cross two lines you get a point where they meet

A point is a solution.

So if the lines never cross, then they would have no point, or A, No Solution

Answer: 30 goldfish

Step-by-step explanation: Bruce has 18 goldfish. If Isabelle has 5 times as many goldfish as Bruce she will have 18*5=90 goldfish. If Arlene has 1/3 times as many goldfish as Isabelle she will have 90/3=30 goldfish.
