Answer: 12 = r
Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.
First, let's put our variables on the right side by subtracting 3r from both sides of the equation. That gives us 5 = 2r - 19.
Now we can move our numbers to the left by adding 19 to both sides of the equation and we get 24 = 2r.
Divide both sides by 2 and 12 = r
Note:
Don't just do this problem in your head. It's extremely important to develop the habit of putting all your steps down on paper or digitally. It will really pay off for you down the line.

The volume of the cylinder will be 900π cube cm.
Step-by-step explanation:
Given,
The volume of the cylinder 225π cube cm
Let the radius be r and the height be h.
To find the volume when the radius is doubled.
Formula
The volume of cylinder = π
According to the problem,
π = 225
When the radius is 2r the volume will be = π
=4π
=4×225π cube cm
= 900π cube cm
