Answer :
Answer: 828π ft³
Step-by-step explanation:
There is a sphere and a cylinder
The volume of a sphere is 4/3πr³
The volume of a cylinder is πr²h
r would be 6ft since 12 ft is the diameter.
h would be 15ft, since that's the height of the cylinder
The sphere's volume is 4/3π(6)³
4/3π216
= 288π
The cylinder's volume is π(6)²(15)
π36·15
540π
Total Volume is the sphere + cylinder
288π + 540π = 828π ft³
