A certain food supplement is 13.2% protein by mass; the density of the supplement is 1.20 g/mL. How many mL of it would contain 835 mg of protein? Metal A has a density of 4.46 g/cm^3. Metal B has a density of 6.78 g/cm^3. A cylinder made of A has the same mass as a block of B whose volume is 34.8 cm^3. What is the radius, in cm, of the cylinder of A if its length is 4.62 cm?
