Function: Creating a Circle
Problem Statement:
The createCircle function will draw a circle with a radius of 7, centered on a specific ordered pair. Use the createCircle function to draw two circles centered at: (0,0) and (12,0). For a challenge add trace blocks to only have the robot draw the two circles without any other marks on the grid.
```/* Code generated by RoboBlockly v2.0 */
double trackwidth = 3.69;
int count;

// Describe this function...
void createCircle() {
robot.traceOff();
robot.traceOn();
count = 0;
while(count < 36) {
count = count + 1;
}
}

createCircle();
robot.traceOff();
