Answer:
18pi units³ or 56.5 units³ (3 sf)
Step-by-step explanation:
pi×r²×h - (4/3)(pi×r³)
r = 3 h = 2r = 6
pi(3²×6 - (4/3)(3³))
18pi units³
Won’t it look the same because you are basically rotating it in a full circle
Is means equal in mathematics
of means multiplication
and if we are solving for x then we can translate your equation to:

Simplifying that more, we get:

And your final answer is:
