Use function files in MatLab to solve: 

**Exercise 5: Calculating the Area of a Circle Using a User-Defined Function** The equation for the area of a circle is given by: \[ A = \pi r^2 \] where: - \( A \) is the area of the circle, - \( r \) is the radius of the circle, - \( \pi \) is a constant approximately equal to 3.14159. **Task:** Create a user-defined function that calculates the area of a circle as a function of its radius. **Output Specification:** The function should display the result in the command window. The output should be formatted as: ``` The area of a circle with radius XXXX is XXXXX. ``` **Example:** If the radius \( r \) is 5, the function should compute the area as \( \pi \times 5^2 \), and the output will be: ``` The area of a circle with radius 5 is 78.54. ``` This exercise is intended to practice creating functions and formatting output in programming.
