Chapter 2, Problem 94E

Interpretation Introduction

Interpretation:

Pound (lb.) is the unit of mass. Feet (ft.) is the unit of length. $Gram/c{m}^3\left(g/c{m}^3\right)$ is the unit of density

Concept introduction:

Density is defined as the ratio of mass and volume.

$\text{Density}=\frac{\text{Mass}}{\text{volume}}$

Rearranging equation,

$\text{volume}=\frac{\text{mass}}{\text{density}}$

To determine:

The approximate percent increase in waist size that occurs when a $155$ lb. person gains $40.0$ lbs.’ of fat. Assume that the volume of the person can be modeled by a cylinder that is $4ft$ tall.
