pleaswe i need help, how do you work out the cross sectional area of a cylinder?
HELP QUICK
and also what the heck i an elasticty module
>Sigh<... Go reread the chapter and do a couple practice problems. Anyway, good luck. 
what's the exact question you are looking at? we can probably help guide you in the right direction if you post the question. i hope nobody actually posts the answer!
try math.com or wikipedia. good luck finding impossible answers! 
Quite evident that you did not even bother to google it..
I dont think there is any point in helping you when you are not intent on putting any effort into it.

It appears to tbe the finite amount you can stretch people's patience before it breaks.
Good luck anyway.

I believe it involves pi and the area of a circle
As others have mentioned, if you do some searching around, you'll find it
To get the area in a cross section would be diameter*height.
To get the area of a circle it would be PI * (r * r)
To get the volume of use PI * (r * r) * height
r= radius

do you mean modulus? I don't know of an elasticty module, but I have learned of Young's Modulus, the shear modulus, and the bulk modulus in physics, and they offer mathematical formulas to quantify and predict the elasticity of materials...
