Answer:
y = 23/3
Step-by-step explanation:
Simplify both sides of equation
7 = y + -2/3
Flip equation
y + -2/3 = 7
Add 2/3 to both sides
y + -2/3 + 2/3 = 7 + 2/3
y = 23/3

Answer:
or 
Step-by-step explanation:
The volume of a cylinder can be found with the following formula:

Where "r" is the radius and "h" is the height of the cylinder.
In this case, let be:
-
the volume of one of this cylinders and
the volume of the other one.
-
the radius of the first one and
the radius of the other cylinder.
-
the height of one of them and
the height of the other cylinder.
Then:

Therefore, you know this:

Simplifying, you get:

Now, knowing the ratios given in the exercise, you can substitute them into the equation:

Evaluating, you get:
