Answer: 154 cu. in
Step-by-step explanation:
The space you have to measure is a cylinder.
Its height is the same as the height of the pipe, 16 inches.
Its diameter =inner diameter of pipe
= outer diameter of pipe - thickness of walls at each end of diameter
= 6 - 2(1.25)
= 3.5 inches
radius r = 1.75 inches
A cross-section of the cylindrical space is a circle.
area of circle = πr² = π * 1.75² = 9.625
volume = area of circle * height
9.625 * 16
= 154 cu. in.
