Drawing a Circle using OpenGL ES 2.0

Hiii ,

Is it possible to draw a circle in C (hollow and filled) using OpenGL ES 2.0 only ? (Without using GLUT /GLFW etc)
I have to use only GLES2 and EGL.
If yes then please let me know how can I do that. If any source code or example code is available please share.It will be helpful.

Thanks and regards …
