The problem is asking how much water remains after 200 glasses of water, each shaped like the given diagram, have been filled from a larger container.

### Step 1: Calculate the volume of one glass of water
The formula for the volume of a cylinder is:

\[
V = \pi r^2 h
\]

Where:
- \( r \) is the radius of the base,
- \( h \) is the height of the cylinder, and
- \( \pi = \frac{22}{7} \) (as given in the problem).

From the diagram:
- Diameter of the base = 6 cm, so the radius \( r = \frac{6}{2} = 3 \) cm.
- Height \( h = 7 \) cm.

Substitute the values into the volume formula:

\[
V = \frac{22}{7} \times 3^2 \times 7
\]

Let me calculate the exact volume of one glass.The volume of one glass of water is \( 198 \, \text{cm}^3 \).

### Step 2: Calculate the total volume of water used for 200 glasses
The total volume of water used for 200 glasses is:

\[
\text{Total Volume} = 200 \times 198 = 39600 \, \text{cm}^3
\]

### Step 3: Calculate the remaining water in the container
Since the total volume used is 39600 cm³, the remaining water will depend on the original volume of the container, which isn't provided in the question. You'll need that information to find out how much water remains.

Do you have the total volume of the container, or should I proceed assuming a specific volume?

Here are 5 related questions to help understand this problem further:
1. How do we calculate the surface area of a cylinder?
2. If the diameter of the base changed, how would it affect the volume?
3. How would you calculate the total volume if the height of each glass changed?
4. What would be the remaining volume if the container held 50,000 cm³ of water initially?
5. How would the answer change if \( \pi \) were taken as 3.1416 instead of \( \frac{22}{7} \)?

**Tip:** The volume of a cylinder depends quadratically on the radius, so even small changes in the radius can significantly affect the total volume.

Air minuman telah diisi penuh ke dalam bekas air tersebut. 200 gelas air minuman seperti rajah di bawah telah digunakan. Berapakah baki air minuman dalam bekas air tersebut? (Gunakan π = 22/7, rumus isi padu silinder = πr^2h)

This problem involves calculating the remaining water in a container after using 200 cylindrical glasses. The solution includes using the volume formula for a cylinder (V = πr^2h) and applying basic algebra to find the final answer. Suitable for students in Grades 6-8.
