OK BY :D. MAKE ME BRAINLIEST OKAY...

Answer 2

Answer:

✴ Inside diameter of the pipe is $\sf {1\frac {15}{16}cm }$ ✴

Step-by-step explanation-

Given,

• Outside diameter = $\sf { 3.5 cm}$
• Wall thickness = $\sf { \frac {25}{32}}$

To find-

• Inside diameter of pipe.

Solution-

As outside diameter given= 3.5cm

Radius = $\sf { \frac{3.5}{2} cm = 1.75cm}$

☆ Inner radius = Outside radius - thickness of pipe ☆

$\sf {=> 1.75- \frac {25}{32} }$

$\sf { =>\frac {175}{100}- \frac {25}{32}= \frac {31}{32} }$

$\sf {=> \frac {31}{32}}$× $\sf {2}$

( radius to convert into diameter)

$\sf {=> \frac {31}{16}= 1\frac {15}{16}cm }$ Ans..
