The Perfect Vase: Finding the Ideal Circle for Liliana's Creation

When it comes to creating a beautiful vase, the base is a crucial element that sets the tone for the entire piece. Liliana, an aspiring artist, wants to create a stunning vase with a circular base that meets her specific requirements. In this article, we will explore the mathematical concept of circles and how to find the ideal circle that represents the base of Liliana's vase.

Liliana wants the area of the base to be between $195 \, \text{cm}^2$ and $155 \, \text{cm}^2$ . To find the ideal circle, we need to determine the range of radii that satisfy this condition. The area of a circle is given by the formula:

A = \pi r^2

where $A$ is the area and $r$ is the radius.

Calculating the Minimum and Maximum Radii

To find the minimum and maximum radii, we can rearrange the formula to solve for $r$ :

r = \sqrt{\frac{A}{\pi}}

Using the given values, we can calculate the minimum and maximum radii:

Minimum radius: $r_{\text{min}} = \sqrt{\frac{155}{3.14}} \approx 6.04 \, \text{cm}$
Maximum radius: $r_{\text{max}} = \sqrt{\frac{195}{3.14}} \approx 8.03 \, \text{cm}$

Finding the Ideal Circle

Now that we have the minimum and maximum radii, we can determine the range of circles that represent the base of Liliana's vase. The ideal circle must have a radius between $6.04 \, \text{cm}$ and $8.03 \, \text{cm}$ .

Visualizing the Solution

To visualize the solution, we can create a graph with the radius on the x-axis and the area on the y-axis. The graph will show the range of areas that correspond to the minimum and maximum radii.

import matplotlib.pyplot as plt

# Define the minimum and maximum radii
r_min = 6.04
r_max = 8.03

# Calculate the corresponding areas
A_min = 3.14 * r_min**2
A_max = 3.14 * r_max**2

# Create the graph
plt.plot([r_min, r_max], [A_min, A_max])
plt.xlabel('Radius (cm)')
plt.ylabel('Area (cm^2)')
plt.title('Ideal Circle for Liliana\'s Vase')
plt.show()

In conclusion, the ideal circle that represents the base of Liliana's vase must have a radius between $6.04 \, \text{cm}$ and $8.03 \, \text{cm}$ . This range of radii ensures that the area of the base falls within the specified limits of $195 \, \text{cm}^2$ and $155 \, \text{cm}^2$ . By understanding the mathematical concept of circles and using the formula for the area of a circle, we can find the perfect circle that meets Liliana's requirements.

Additional Tips and Variations

To create a more realistic vase, Liliana can experiment with different shapes and sizes of circles.
She can also use different materials, such as glass or ceramic, to create a unique and eye-catching vase.
For a more challenging project, Liliana can try creating a vase with a non-circular base, such as a square or a triangle.

Final Thoughts

Creating a beautiful vase requires a combination of artistic skill and mathematical knowledge. By understanding the concept of circles and using the formula for the area of a circle, Liliana can create a stunning piece of art that meets her specific requirements. Whether you're an aspiring artist or a math enthusiast, this project is a great way to explore the intersection of art and mathematics.
