To find the volume of a water container that has the shape of a cylinder, you can use the formula:

$V = \pi r^2 h$

where:

• $V$ is the volume of the cylinder,
• $\pi$ is approximately $\frac{22}{7}$,
• $r$ is the radius of the base of the cylinder,
• $h$ is the height of the cylinder.

Given that the formula you provided is $\pi j^2 t$, it seems $j$ represents the radius and $t$ represents the height, which matches the standard formula.

To find the volume, plug in the values for $j$ (radius) and $t$ (height):

$V = \frac{22}{7} \times j^2 \times t$

If you provide the specific values for $j$ and $t$, I can calculate the exact volume for you.

Would you like to provide those values, or do you have any other questions? Here are some related questions to consider:

1. How do you convert the volume from cubic units to liters?
2. What is the surface area of a cylinder, and how do you calculate it?
3. How does changing the radius affect the volume of a cylinder?
4. How does changing the height affect the volume of a cylinder?
5. What are practical applications of calculating the volume of cylinders in real life?

Tip: Always ensure the units of radius and height are the same before calculating the volume to avoid errors in measurement.
