The candle has the shape of a cylinder with height H=6 in, and radius of the circular base R= (2.8)/2 =1.4  (in).

The volume of the cylinder is Area(base)*height = 

[tex] \pi R^{2} *H=3.14* (1.4)^{2}*6= 37[/tex]   (in cubed)

According to Cavalieri's principle, the volume of the candle is equal to the volume of the cylinder we described.

Answer: 37 in cubed
