Question

In Python:

Define a function drawCircle. This function should expect a Turtle object, the coordinates of the circle’s center point, and the circle’s radius as arguments. This function should draw the specified circle. The algorithm should draw the circle’s circumference by turning 3 degree and moving a given distance 120 times. Calculate the distance moved with the formula 2.0*π*radius/120.0.

Answer 1

code

import turtle

from math import pi

def draw_circle(myTurtle, x, y, radius):

myTurtle.penup()

myTurtle.setposition(x, y-radius) # move to the position x,y-radius where x ,y will be center

myTurtle.pendown()

for i in range(120):

myTurtle.circle(radius, 3)

turtle.getscreen().mainloop()

distance_moved = 2.0*pi*radius/120.0

return distance_moved

myTurtle = turtle.Turtle()

distance = draw_circle(myTurtle, 200,200 ,50)

on console:

   
2.61799387799
   

print(distance)
