how to make uv? i want used in paper coating?
does this uv mean ultra violet light ? is this like you want to make a portable light for the purpose of some type of inspection light try Radio Shack or an electronics online store for parts if you are looking for a sun capture for quick tanning then it would be a cardboard with glued on aluminum foil .
for the 1st: by using the volume of cylinder equation: V (PI)R^2H WE GET : 18.8 inch^3 for the 2nd: WE use the volume of cylinder and sphere to get184.3 mm^3
