Question

5. A water pipe has an outside diameter of 13.5 cm and a wall thickness of cm. 12/13 What is the inside diameter of the pipe?​

Answer 1

Answer:

1.94 cm

Step-by-step explanation:

Inside diameter = 3.5 cm

Wall thickness = 0.78 cm

So, in order to find the inside diameter of the pipe, we can subtract two times of wall thickness from the outer diameter, In mathematical terms, it can be written as:

Inner diameter = outer diameter - 2* (wall thickness)

Putting the values in these equations:

Inner diameter = 3.5 - 2*(0.78)

Inner diameter = 1.94 cm
