In the following code: size = 20 x = 100 y = 200 ball = Circle(size) circle.set_position(x, y) What is the meaning of the x variable? The x coordinate of the left side of a box that would hold the circle The x coordinate of the right edge of the circle The radius of the circle The x position of the center circle

The following code should draw a circle on the screen. def draw_circle(x, y, radius): circle = Circle(radius) circle.set_position(x, y) Python But when we run this code, we don't see the circle. What is missing? Since we are trying to create a circle, we need to use the create_circle command. The code will have an error need to define the position when you create the the circle To add the circle to the canvas, you need to use the circle.add() command To add the circle to the canvas, you need to use the add(circle) command

To add the circle to the canvas, you need to use the add(circle) command

We want to simulate constantly flipping a coin until we get 3 heads in a row. What kind of loop should we use? For loop While loop Loop and a half Infinite loop

While loop

The following program should draw a circle on the screen def draw_circle(x, y): circle = Circle(100) circle.set_position(x, y) Python But when we run this code, we don't see the circle. What is missing? Since we are trying to create a circle, we need to use the create_circle command. The code will have an error since you need to define the color. You need to add the circle with the circle.add() command. You need to add the circle with the add(circle) command.

You need to add the circle with the add(circle) command.

If you wanted to use the following code to draw a circle to the canvas with the radius, and x and y coordinates given by the user, how would you ask for this information? circle = Circle(radius) circle.set_position(x, y) x = input("What is the x coordinate? ") y = input("What is the y coordinate? ") radius = input("What is the radius of the circle? ") x = int(input("What is the x coordinate? ")) y = int(input("What is the y coordinate? ")) radius = int(input("What is the radius of the circle? ")) x = input("What is the x coordinate? ") y = input("What is the y coordinate? ") radius = int(input("What is the radius of the circle? ")) x = int(input("What is the x coordinate? ")) y = int(input("What is the y coordinate? ")) radius = input("What is the radius of the circle? ")

x = input("What is the x coordinate? ") y = input("What is the y coordinate? ") radius = int(input("What is the radius of the circle? "))

We want to position a Circle on our screen to be at a random position, but we want to keep the entire shape on the screen. Which of the following will accomplish this given the following function? (Assume SIZE, HEIGHT, and WIDTH are properly defined) def draw_circle(x, y, radius): circle = Circle(radius) circle.set_position(x, y) add(circle) x = random.randint(0,WIDTH) y = random.randint(0,HEIGHT) draw_circle(x, y, SIZE) x = random.randint(SIZE,WIDTH-SIZE) y = random.randint(SIZE,HEIGHT-SIZE) draw_circle(x, y, SIZE) x = random.randint(0,HEIGHT) y = random.randint(0,WIDTH) draw_circle(x, y, SIZE) x = random.randint(SIZE,HEIGHT-SIZE) y = random.randint(SIZE,WIDTH-SIZE) draw_circle(x, y, SIZE)

x = random.randint(SIZE,WIDTH-SIZE) y = random.randint(SIZE,HEIGHT-SIZE) draw_circle(x, y, SIZE)
