var color = Randomizer.nextColor();
var centerX = getWidth()/2;
var centerY = getHeight()/2;
var radius = 100;
drawCircle(centerX, centerY, radius, color);
}"

Answer 1

This program is written in JavaScript and it draws a circle on a canvas using three functions: drawCircle, start, and draw.

Step-by-step explanation:

This program is written in JavaScript and it draws a circle on a canvas. The program consists of three functions: drawCircle(x, y, radius, color), start(), and draw().

The drawCircle function creates a new circle object with the given radius and sets its position and color. The circle object is then added to the canvas.

The start function sets a timer to call the draw function every 50 milliseconds.

The draw function generates a random color, calculates the center of the canvas, and calls the drawCircle function to draw a circle at the center with a radius of 100 and the random color.
