Dear student
 
While drawing ray diagrams , remember that the distance of center of curvature from the pole is always equal to twice the distance of the focus from the pole. For instance, if the distance of the focus from the pole (focal length) is taken as 2 cm then the distance of center of curvature from the pole (radius of curvature) should be take as 4 cm.
Focus as well as the radius of curvature lies on the principal axis.
 
We hope this clarifies your doubt.
