its very simple halp...see i the exam u wud not be asked to use this formula,....u'd be asked to make a sketch diagram..bt this is for ur own reference nd checking....simply put the values in the formula nd take out the required thing
f- focal length
So-distance of object from the center
Si-distance of image from the center

u shud specify from the centre of the lens, oh yeh and about that q, i cancelled the area like aadi says. but if u want to knw the area of cross-section, its the same, if u really want to explain it u shud also say that the area of cross-section of the piston stays constant cuz the examiner can assume that the area of cross section of the cylinder remains constant (just to make it look as u knw what ur talkin about ;) )

hey guys do we need to know this relationship:
Resistance= (constant*length)/area of cross-section
???
just saw it in the study guide....i know its simple to remember and use both...m just asking for curiosity....
