The volume of the metal in the cylindrical pipe is 86.40π mm³.
What is the volume of the metal in the pipe?
The volume of the metal in the pipe is the difference between the volume of the metal pipe and the volume of the hole.
Volume of a cylinder = πr²h
Where :
π = pi
r = radius = diameter / 2
h = height
Volume of the metal in the pipe = π x 10[ ( 8.4/2)² - (6/2)²] = 86.40π mm³
