Chapter 1.1, Problem 29PPS

To determine

To calculate:Expression for the volume.

Answer to Problem 29PPS

The expression for volume is $\pi r^{2}h$ .

Explanation of Solution

Given information:The volume of a cylinder is $\pi$ times the radius $r$ squared multiplied by the height $h$ .

Calculation:

The term “radius $r$ squared” denotes $r$ multiplied twice that is $r\times r=r^2$

The term “ $\pi$ times the radius $r$ squared” denotes $\pi$ multiplied by $r^2$ that is $\pi r^2$

The term “ $\pi$ times the radius $r$ squared multiplied by the height $h$ ” denotes $\pi r^2$ multiplied by $h$ that is $\pi r^{2}h$ .

Thus, the expression for volume of a cylinder is $\pi r^{2}h$ .
