Yes. You and Elena are correct.
It has the prefix bio, it is probably about biological stuff or in other words life.

Please post your own question separately. Otherwise Elena or I may not see it because were assume this is about biology and we have already answered.
Anyway
mass = density * volume
look up density of iron (about 8 grams /cm^3)
mass = about 8 * 247 * pi * 2.6^2/4
in grams. Divide by 1000 to get kg
