Complete the Famous Painting
Problem Statement:

The masterpiece is almost complete-- you just need to paint the green apple in front of his face! The pre-placed blocks will help you draw a circle (the apple). Please modify the blocks so that the circle will have a radius of 2.5 and is at the center of his face (12, 12).

```/* Code generated by RoboBlockly v2.0 */
/* Problem Statement:
Please draw a green circle (the apple) in front of his face
to complete the painting. The circle should have a radius
of 2.5 and placed at the center of his face, which is at
(12, 12).
