-52/7 = 7 3/7
I think the answer is Fe+02=fe 203
Answer:
Answer3. 9.9cm^3
Step-by-step explanation:
First calculate the volume of the whole pencil. Next, calculate the volume of the lead. Last, subtract. Take away the volume of the lead from the volume of the pencil:
VolWood =
VolPencil - VolLead
First, Volume of the pencil:
vol = pi•r^2•h
= 3.14•(.4)^2•21
= 10.5504 cm^3
Next, volume of lead:
vol = pi•r^2•h
= pi•(.1)^2•21
= .6594cm^3
Last, subtract:
VolWood =
VolPencil - VolLead
= 10.5504 - .6594
= 9.891
~= 9.9cm^3
The volume of the wood is 9.9cm^3.
