Cavalieri's principle states that if two solids of equal height have equal cross-sectional areas at every level parallel to the respective bases, then the two solids have equal volume.
That is not true there is a person and that person is called god and he created us sense day one and he sent down Jesus to die on the cross for our sins and he went through the worst thing imaginable just to save us from our sins. If you don’t believe me look it up and it will tell you who created us so you should be thankful you are here today if it wasn’t for Jesus you would not be here who ever said that is wrong trust me.
Answer:
20165
Step-by-step explanation:
Given:
Length/height (h) of cylindrical test tube = 152 mm
Radius of cylindrical test tube = 6.5 mm
Volume = 
Required:
Volume of cylinder to nearest whole number
Solution:
The volume is given as 
Take π as 3.14 and plug the values of r and h into the volume formula.
Volume of the test tube = 20165 mm³ (nearest whole number)
