Question

Please help with this

Answer 1

Here

radius( r) =12/2=6 in.

height(h)=13 in.

now,

volume of hemisphere(V1)=

$\frac{2}{3} \pi \: {r}^{3} = \frac{2}{3}\pi {6}^{3} = 144\pi \: cu. \: in.$

volume of cylinder(V2)=

$\pi {r}^{2} h = \pi \times {6}^{2} \times 13 = 468\pi$

now total volume=V1+V2

=144Pi +468pi

=212pi
