Chapter 12.6, Problem 13PPS

To determine

Calculate the surface area of hollow cylinder.

Answer to Problem 13PPS

Surface area of hollow cylinder is $196.626i{n}^2$

Explanation of Solution

Given:

  

Calculations:

Here, we have to calculate surface area of hollow cylinder.

We know that, surface area of hollow cylinder is calculated as,

  $Surfacearea=2\pi (r_1+r_2)(r_2-r_1+h)$

Where, $r_2$ is the radius of outer cylinder

  $r_1$ is the radius of inner cylinder

h is the height of cylinder

Putting values in equation, we get

  $\begin{array}{l}Surfacearea=2\pi (r_1+r_2)(r_2-r_1+h)\\ =2\times 3.14(1.5+1.6)(1.6-1.5+10)\\ =196.626i{n}^2\end{array}$

Conclusion:

Therefore, we are able to calculate surface area of hollow cylinder using simple formula.
