Twenty Circles
Problem Statement:
Modify the blocks so that the robot traces over the twenty circles.

// Repositions the robot to the next starting point of the next circle
void nextCircle() {
  robot.drivexyTo(11 * cos(deg2rad(degrees)), 11 * sin(deg2rad(degrees)), radius, trackwidth);
  robot.turnRight(11, radius, trackwidth);
}

// Create a circle of given radius

  while(count < 360) {
    robot.setSpeed(25, radius);
    robot.driveDistance(double((radius * (2 * M_PI)))/360, radius);
