We only need focal length and the object distance to solve this problem.
The sun is 150,000,000 km from earth; its diameter is 1,400,000 km. A student uses a 5.2-cm-diameter lens with f = 10 cm to cast an image of the sun on a piece of paper.
Where should the paper be placed relative to the lens to get a sharp image?
