How many test tubes can Braddock prepare?
Use 3.14 to approximate pi, and round your final answer to the nearest whole number.
Braddock should prepare 6 test tubes.
height = 40mm
radius = 12 mm
pi = 3.14
volume of test tube = 3014 mm³
We need to get the volume of the cylinder to know how much saline solution it holds.
Volume = π r² h
= 3.14 * (12mm)² * 40mm
= 3.14 * 144mm² * 40mm
Volume = 18,086.40 mm³
To get the number of test tubes used: we need to divide the volume of the cylinder by the volume of the test tube.
18,086.40mm³ / 3014mm³ = 6 test tubes.
