Ответ:
332 cubic inches
Step-by-step explanation:
Given : Height of cylinder = 14 inches
Diameter of Base(including thickness = 8 inches
The wall of the pipe is 1.25 inches thick.
To find: What is the approximate inside volume of the pipe?
Solution:
Diameter including thickness = 8 inches
Since thickness of wall = 1.25 inches
So, diameter excluding thickness from both sides =
=
=
Thus the diameter excluding thickness = 5.5 inches
Radius of cylinder =
Volume of cylinder =
Where r is the radius
h is the height
Substitute the values .
Volume of cylinder =
=
Thus the approximate volume of cylinder is 332 cubic inches.
Hence Option C is correct.
