Answer:
972π cm³
Step-by-step explanation:
Okay so this container is a sphere, so you're going to want to use the volume of a sphere equation V = (4/3) * π * r³. In this case, you've got the diameter (d = 18), so divide by 2 to get r = 9.
So now you have all the variables you need to solve. Substituting those values into the volume equation, you get:
V = (4/3) * π * 9³ = 972π cm³.
