The problem asks if Frau Schlie needs to buy more soil to plant 4 flower pots. She currently has 80 liters of soil. Each flower pot is shaped like an inverted cone, with a diameter of 50 cm and a height of 30 cm.

To solve this:

1. **Calculate the volume of one cone-shaped flower pot** using the formula for the volume of a cone:
   \[
   V = \frac{1}{3} \pi r^2 h
   \]
   where:
   - \( r \) is the radius of the base of the cone (half of the diameter),
   - \( h \) is the height of the cone.

2. **Convert units** if needed, as the current soil quantity is in liters (1 liter = 1000 cubic centimeters).

Let me calculate it.The total volume of soil needed to fill 4 flower pots is approximately 78.54 liters. Since Frau Schlie has 80 liters of soil, she does **not** need to buy more soil, as the available amount is sufficient.

Would you like more details, or do you have any questions?

Here are 5 related questions to explore further:
1. How would the required volume change if the diameter of the pots increased?
2. What if the height of the pots were reduced by 5 cm—how much soil would be needed then?
3. How do you calculate the volume of a cylinder-shaped pot instead of a cone?
4. What would happen if the number of pots increased to 6?
5. How much extra soil would be left over after filling the 4 pots?

**Tip:** Always check the units in your problem, especially when dealing with volume.

Frau Schlie wants to plant 4 flower pots. She has 80 liters of soil. Each pot has a diameter of 50 cm and a height of 30 cm. Does she need to buy more soil?
