What does the MAX_RADIUS variable limit in the Growing Circle program?

The MAX_RADIUS variable is designed to set a limit on the maximum size that the radius of the circle can reach within the program. By establishing this variable, the program can ensure that the circle does not exceed a certain size, which is crucial for maintaining visual coherence and functionality in the animation.

For instance, if the radius were allowed to grow indefinitely, it could lead to display issues, hinder user interactions, or even disrupt the overall aesthetics of the animation. By enforcing a maximum radius, the program can effectively control the growth of the circle, providing a boundary that prevents it from becoming too large and overwhelming the canvas or altering the intended design of the animation.

Other options like maximum number of colors, maximum number of circles drawn, and maximum height of the canvas pertain to different aspects of the program. They do not directly relate to the specific limitation placed on the size of the circle's radius, which is the primary function of the MAX_RADIUS variable.
