I'm not 100% sure, but I think the answer is 395.6. If you multiply 14 by 9, you get 126, multiply that by 3.14, and you get 395.64, then round it to the nearest tenth, and you get 395.6.

We're going to first have to find the volume of the cone.
(1/3) Bh where B stands for the area of base.
(1/3)[tex] \pi [/tex](9)²×14
1186.92 in³

Now, we'll find the volume of the semi-sphere.
(4/3)[tex] \pi [/tex](9)³
3052.08 in³

Now, in order to find the total, we have to add the two values together: 1186.92 + 3052.08 = 4239 in³
