Braddock should prepare 6 test tubes.
Given:
cylinder:
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.
There's a 30 coefficient on the first and no coefficient (i.e. a 1) on the second. So the GCF of the constant part is GCF(30,1)=1.
Similarly, because both have as a factor.
because both have as a factor.
Now that we see how the bits work it's not too hard to read these off:
