Answer:

\large\boxed{972\pi\ cm^3}

Step-by-step explanation:

\text{The formula of a volume of a sphere:}\\\\V=\dfrac{4}{3}\pi R^3\\\\R-radius\\\\\text{We have the diameter of the sphere.}\ D=18cm.\\\\D=2R\to R=\dfrac{18}{2}\ cm=9cm.\\\\\text{Substitute:}\\\\V=\dfrac{4}{3}\pi(9^3)=\dfrac{4}{3}\pi(729)=(4)\pi(243)=972\pi\ cm^3

V=4/3pi(18)^3

V=7776pi

wolverine [178]
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 = 

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

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