Question

Inner radius of pipe is 10.24 mm and outer radius of pipe is 13.64 mm. what is the thickness of pipe ?

• A. $\frac{34}{50}\text{mm}$
• B. $\frac{17}{5}\text{mm}$
• C. $\frac{17}{50}\text{mm}$
• D. None of the above

Answer 1

The correct option is B $\frac{17}{5}\text{mm}$

Given,
Inner radius of pipe = 10.24 mm
Outer radius of pipe = 13.64 mm
thickness of pipe will be = (outer radius $-$ inner radius)
$=(13.64-10.24)\text{mm}=3.4\text{mm}$

Converting it into fraction we get,
$\Rightarrow 3.4=\frac{34}{10}=\frac{17}{5}\text{mm}$

So, the thicknes of pipe will be $\frac{17}{5}\text{mm}$
