Answer 1

you can draw it randomly

Answer 2

it's not necessary to take measurement and draw focus and Center of curvature. We can just draw it randomly because the evaluators won't measure it but make sure you draw the ray diagrams properly and neatly and label neatly and visibly dark.

Hope it helps you..
