8218.406
Go through the process yourself to make sure my answer is correct

Explanation:

The best way to solve these problems is by breaking them up into the difference shapes you see

A. Semi-sphere

The volume of a sphere is
`(4)/(3) \pi r^3`. Since we have a semi-sphere, we divide this by 2 and get:

`V=(4)/(6) \pi r^3\\\\V= (4)/(6) \pi (12)^3\\\\V=3619.115`

B. Cone

The volume of a cone is
`\pi r^2(h)/(3)`

`V = \pi (12)^2(30.5)/(3)\\V = 4599.292`

C. Add

Add these two values:

3619.115 + 4599.292 = 8218.406
