R>4cм<5см=4,5см
4cм<4,5cм<5см

Answer 2

Building a Circle with a Given Radius

To build a circle with a center at point B and a radius greater than 4 cm but less than 5 cm, you can follow these steps:

1. Determine the Center Point: Identify the coordinates of point B where the center of the circle will be located. 2. Choose the Radius: Select a radius that is greater than 4 cm but less than 5 cm.

Example Coordinates and Radius

Let's assume the coordinates of point B are (x, y) and the chosen radius is 4.5 cm.

Code for Drawing the Circle

You can use the following code to draw the circle with the given center and radius using a suitable programming language and graphics library:

import matplotlib.pyplot as plt
import numpy as np

# Coordinates of the center
center = (x, y)

# Radius of the circle
radius = 4.5

# Create an array of angles from 0 to 2*pi
theta = np.linspace(0, 2*np.pi, 100)

# Parametric equations to generate x and y coordinates of the circle
x_circle = center[0] + radius * np.cos(theta)
y_circle = center[1] + radius * np.sin(theta)

# Plot the circle
plt.plot(x_circle, y_circle)
plt.plot(center[0], center[1], 'ro')  # Mark the center point
plt.axis('equal')  # Ensure aspect ratio is 1:1
plt.show()

This code uses the `matplotlib` library in Python to plot the circle with the given center and radius. You can adjust the coordinates of the center and the radius as per your specific requirements.

Remember to replace `(x, y)` with the actual coordinates of point B and `4.5` with the chosen radius.
