A compass perhaps?
The best tool to locate the center of a circle would be a compass. By placing the compass on the edge of the circle and drawing an arc, then repeating this process from another point on the circle, the intersection point of the arcs will give you the center of the circle.
if you are drawing a circle with the help of circle tool in computer with paint, you will find that if you zoom it,the circle is made with small lines.

To create a dome in Google SketchUp, start by drawing a circle using the Circle tool at the desired base diameter. Then, use the Push/Pull tool to extrude the circle into a hemisphere by pulling it up to the desired height. Alternatively, you can use the Arc tool to create a half-circle profile and then use the Follow Me tool along a vertical path to form a dome shape. Finally, adjust the shape as needed using the Scale or Move tools.
