Define a function drawcircle. this function should expect a turtle object, the coordinates of the circle's centerpoint, and the circle's radius as arguments. the function should draw the specified circle. the pen color should bechanged to yellow before drawing a circle and the width of the pen to 5 pixels. the algorithm should draw the circle's circumference by turning 3 degrees and moving a given distance 120 times. calculate the distance moved with theformula 2.0*n*radius/120.0. fill in the circle with blue color. after drawing the circle, hide the turtle. my instructor told me that i have to use the formula not the circle function to make this work. you! import turtleimport mathdef drawcircle(centerpoint, radius): degree = 3count = 0centerpoint = (2.0 * math. pi * radius / 120)t. home()t. setheading(degree)while count < = 120: t. down()t. forward(2.0 * math. pi * radius / 120)t. up()degree += 3t. setheading(degree)count += 1drawcircle(centerpoint, radius)
