A water pipe has an outside diameter of 3.5cm and a wall thickness of 25/32cm. What is the inside diameter of the pipe?
Answers
Answer:
A water pipe has an outside diameter of 3.5cm and a wall thickness of 25/32cm
inside diameter of the pipe = 31/16 cm (1.9375 cm)
Step-by-step explanation:
Out side diameter of pipe = 3.5 cm
Wall thickness of pipe = 25/32 cm
Inside diameter = outside diameter - wall thickness - wall thickness
Thickness is reduced twiced because its diameter
if it has been radius then thickness would have reduced only once
=> Inside diameter of the pipe = 3.5 - 25/32 - 25/32
= 3.5 - 25/16
= (56 - 25)/16
= 31/16 cm
= 1.9375 cm
inside diameter of the pipe = 31/16 cm (1.9375 cm)
Answer:
The inside of the diameter of the pipe is 1.9375 cm
Step-by-step explanation:
This is a simple question on shapes and measurements.
Given that we have the thickness and the outer diameter we see that we have inner and outer circle separated by a certain width or thickness.
Inner diameter = Outer diameter - 2(thickness)
Outer diameter = 3.5 cm
Thickness = 25/32 cm
Doing the substitution we have :
3.5 cm - 2 × (25/32) cm
= 3.5cm - 25/16
We could convert both to decimal for easier addition.
3.5cm - 1.5625 = 1.9375 cm
