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:
w = -1.266
Step-by-step explanation:
distribute the 5 by everything in the parenthesis and then bring everyhting down then you should have a regular equation to work w
Answer:
(pi)4 or about 12.57 sq. units
Step-by-step explanation:
The base area of a cylinder is a circle.
Since we know that the radius is 2, we can use the equation A = (pi)r^2 to find the area.
So, using this formula, the area is (2)(2)(pi), about 12.57 sq. units (area is squared!)
C
I think this is the right answer
