Answer:
The volume of the plastic pipe is 141 cubic centimetre
Step-by-step explanation:
Given:
The Length of the plastic water pipe = 12 cm
The inner Diameter of the plastic water pipe = 12 cm
The outer Diameter of the plastic water pipe = 15 cm
To Find:
the volume of the plastic pipe not the hollow interior to the nearest hundredth = ?
Solution:
The volume of the plastic water pipe can be found by using the volume of the cylinder formula
The Volume of the cylinder = 
Where
r is the radius
h is the height
Radius r 
On substituting the values
The Volume of the cylinder
=
=
= 141.37 cubic centimetre
= 141 cubic centimetre
