Question

I need help with this question

Answer 1

684π

Explanation:

It is two parts: half of a sphere and one cylinder.

Sphere volume formula: V=4/3πR³, r=12/2=6, r³=216

v=4/3π216

v=288π

Half of sphere: 288π/2=144π

Cylinder volume: V=πr²h, r=12/2=6, r²=36, h=15,

V=π*36*15=540π

So, total is 144π+540π=684π
