Chapter 12, Problem 15MCQ

To determine

To find the volume of the given cylinder.

Answer to Problem 15MCQ

  $81\pi$ feet³

Explanation of Solution

Given:

  

Radius of cylinder, $r=3$ feet

Height of cylinder, $h=9$ feet

Formula used:

Volume of cylinder, $V=\pi r^{2}h$

Calculation:

For the given cylinder,

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

  $\begin{array}{l}=\pi \times {\left(3\right)}^2\times 9\\ =\pi \times 9\times 9\\ =81\pi \end{array}$

Conclusion:

Therefore, volume of the given cylinder is $81\pi$ feet³.
