Chapter 12.3, Problem 24WE

To determine

To calculate: The inside diameter of the new pipe

Answer to Problem 24WE

The inside diameter of the pipe is 10cm

Explanation of Solution

Given information: Consider the given information,

Inside diameter of first pipe = 6cm

Inside diameter of second pipe = 8cm

Formula used: Consider the given formula,

r = radius, h = height

Volume = $\pi r^{2}h$

Calculation : Consider the given information the formula is,

  $\pi \times {(\frac{6}{2})}^2\times h+\pi \times (\frac{8}{2})\times h=\pi r^{2}h$

  $25\pi =\pi r^2$

  $r=5$

  $=5\times 2=10$ cm
