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.

I believe it involves pi and the area of a circle Very Happy
As others have mentioned, if you do some searching around, you'll find it Wink

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...
