Question

If the smallest markings on a graduated cylinder are one tenth (1/10) of a milliliter, which of the following measurements could be recorded using that graduated cylinder?

10 mL
10.1 mL
10.05 mL
10.050 mL

Answer 1

If the markings on a measurement apparatus are a certain distance apart, we can usually estimate one decimal place beyond that. So for markings 0.1 ml apart, we can estimate to the nearest 0.01 ml, which would be 10.05 in this case.

Answer 2

Both 10 mL and 10.1 mL can be measured accurately with the graduated cylinder

Step-by-step explanation:

• The smallest marking on the graduated cylinder is 0.1 mL

So, 0.1 mL = 1 smallest marking

Hence, 10 mL =
`(1)/(0.1)* 10` smallest marking = 100 smallest markings

Also 10.1 mL =
`(1)/(0.1)* 10.1` smallest marking = 101 smallest markings

So both 10 mL and 10.1 mL can be measured accurately with the graduated cylinder
