3. a prop for the theater club’s play is constructed as a cone topped with a half-sphere. what is the volume of the prop? round your answer to the nearest tenth of a cubic inch. use 3.14 to approximate pi.

We know that
[Volume of a cone]=pi*r²*h/3
and
[Volume of a half-sphere]=(4/6)*pi*r³
then
h=14 in
r=9 in
[Volume of a cone]=pi*r²*h/3> pi*9²*14/3> 1186.92 in³
[Volume of a half-sphere]=(4/6)*pi*r³>(4/6)*pi*9³> 1526.04 in³

the volume of the prop=1186.92+1526.04> 2712.96 > 2713 in³

the answer is 2713 in³

The first one minimumi hope my answer you.
