According to Cavalieri's principle, if two solids have the same height an the same cross-sectional area at every level, then they have the same volume. So the statement that would best describe the relationship between the paperweights according to Cavalieri's principle is that, t<span>he volumes of the paperweights are the same. Hope this helps.</span>

Answer:
see explanation
Step-by-step explanation:
Using the identity
tan x = 
Consider the left side
= 
( multiply numerator and denominator by cos²x to clear fractions
= 
← ( cos²x + sin²x = 1 ]
= cos²x - sin²x
= right side , thus proven
