Option C
The ratio for the volumes of two similar cylinders is 8 : 27
<h3><u>
Solution:</u></h3>
Let there are two cylinder of heights "h" and "H"
Also radius to be "r" and "R"

Where π = 3.14 , r is the radius and h is the height
Now the ratio of their heights and radii is 2:3 .i.e

<em><u>Ratio for the volumes of two cylinders</u></em>

Cancelling the common terms, we get

Substituting we get,



Hence, the ratio of volume of two cylinders is 8 : 27
Set up a system of equations:




x represents how many tee shirts were bought, and y represents how many long sleeve shirts were bought.
For the first equation, subtract y from both sides to get x by itself:

We'll now use substitution. Since x is equal to a value, we can substitute this value for the other equation:

Distribute the 10 to both terms in parentheses:



Combine like terms:


Subtract 90 from both sides:

Divide both sides by -3 to get y by itself:

6 long sleeve shirts were bought.
Now you have a value for y. Input this value into the first equation:

Subtract both sides by 6 to get x by itself:

3 tee shirts were bought.
The answer is B. 3 tee shirts and 6 long sleeve shirts.
Answer: y = 18/32
Step-by-step explanation: Okay the equation is xy = k
You plug in x and y.
(3)(6) = k
18 = k
To get the value of y when x = 32 you plug in 32.
Use this equation now y = k/x
Now it is y = 18/32
And that is your answer!
