Answer:

Volume of the Figure
=825.38m^3

Explanation:

Volume of the figure = Volume of the Upper cone+Volume of the lower cone

Volume of a cone =
$\pi *r^2*(h)/(3)$

Volume of the Upper Cone with

height=12m

radius=6m

3.14*6*6*(12)/(3)

$=3.14*6*6*4\\\\=3.14*36*4\\\\=3.14*144\\\\=147.14m^3$

Volume of the Lower cone with
radius=6m and
height=18m

$=3.14*6*6*(18)/(3) \\\\=3.14*6*6*6\\\\=3.14*36*6\\\\=3.14*216\\\\=678.24m^3$

Volume of the Whole Figure =
147.14+678.24

Volume of the Figure
=825.38m^3
