Hannah plans on going hiking most of the day. It is recommended that she takes at least 3 liters of water with her. She packed 3 water bottles. The bottles she brought are cylinders with a radius of 3cm and a height of 30cm. What is the volume of one bottle to the nearest cubic centimeter?

Question

Hannah plans on going hiking most of the day. It is recommended that she takes at least 3 liters of water with her. She packed 3 water bottles. The bottles she brought are cylinders with a radius of 3cm and a height of 30cm. What is the volume of one bottle to the nearest cubic centimeter?

vol of cyclinder=TTr^2h
TT(3^2cm)(30cm)
v=848.23cm^3 so we round it to 848cm^3

Second part is one cubic centimeter has the same volume as one milliliter. Does Hannah have enough water with her? Explain your answer
848cm^3= (848ml per bottle)(3bottles)
so 2,544ml total= 2.54L total
no Hannah did not have enough water with her. she only had 2.54L between the 3 bottles not 3L.
Is this correct? Thanks for checking my
work for me.

Answer 1

calculations and reasoning are correct. good job.

just to be a stickler: "between" refers to 2 objects. Use "among" for more than two.

Answer 2

ok thanks for your help and the tidpit of useful information

Answer 3

just to be a stickler: that's "tidbit"

:-)

Answer 4

Yes, your calculations are correct. The volume of one water bottle is indeed 848 cm³ (rounded to the nearest cubic centimeter). And when we multiply 848 ml (which is equivalent to 848 cm³) by 3 bottles, we get a total of 2,544 ml or 2.54 liters. Therefore, Hannah does not have enough water with her since she only packed 2.54 liters instead of the recommended 3 liters. Well done on your calculations!
