For proportional errors it needs to be 3 sig figs

Procedure B length = 12.42 mm # 0.01 mm diameter = 4.16 mm + 0.01 mm mass = 1.32 g + 0.01 g proportional error in length = proportional error in diameter = proportional error in mass = cylinder volume = proportional error in cylinder volume = uncertainty in cylinder volume = placed as anticipated (yes, no) cylinder density = proportional error in cylinder density = uncertainty in the density = placed as anticipated (yes, no) (available work space)
