Answer:
20357.5 ft³
Step-by-step explanation:
You want the volume of a cylinder of radius 18 ft and height 30 ft with a cone of the same dimensions removed.
Volume
The volume of the cylinder itself is ...
V = πr²h
The volume of the conical space is ...
V = 1/3πr²h
The remaining volume after the cone is removed is then ...
V = πr²h -1/3πr²h = πr²h(1 -1/3)
V = π(18 ft)²(30 ft)(2/3) ≈ 20357.5 ft³
The volume of the remaining solid is about 20357.5 cubic feet.
