Answer:
GET SCAMMMMMMED KIIDDDD!!!!!!!
Step-by-step explanation:
The volume of the shape
We have a cylinder that is cut into two. Its external radius is 5ft, while its internal radius is 4ft.
External radius = internal radius + thickness

Internal radius = 4ft (given)
Recall that the volume(V) of a full cylinder is:

Since the cylinder is cut into two, the volume(V) is:

height (h) = 12ft (given)
The volume of the shape:
Answer:
2.0
Step-by-step explanation:
Answer:
(64/5)π
Step-by-step explanation:
Area of the circle: 16π
central angle: (8/5)π
The Area of the circle corresponds to a central angle equal to 2π (the complete circle). Then the following proportion must be satisfied:
16π / x = 2π / (8/5)π
x = [16π * (8/5)π] / 2π
x = (64/5)π
