The following is not a method of calculating percentage of body fat is:
Body mass index
Body fat is the amount of fat that is stored in the body of a living organism, or a human being. The healthy fat range for men is about 8-19% and anything above this is considered unhealthy.
There are various ways of calculating percentage of body fat which includes:
Underwater weighing
Bioelectrical impedence
Skinfold measures, etc.
Body Mass Index (BMI) is simply a method or way of measuring the body fat in the body of a person and showing the proportionality between the height and weight of the person.

The moment of inertia for rotation about the perpendicular axis through the edge of the disk is 3.78 × 10⁻⁵ kgm².
<h3>
Moment of inertia</h3>
Moment of inertia is referred to as the product of mass of section and the square of the distance between the reference axis and the centroid of the section.
Moment of inertia of solid cylinder or disk is expressed as;
I = 1/2 × mr²
Given the data in the question;
- Mass of disk m = 21g = 0.021kg
- Diameter of disk d = 12cm = 0.12m
- Radius r = d/2 = 0.12m / 2 = 0.06m
We substitute our given value into the expression above.
I = 1/2 × 0.021kg × (0.06m)²
I = 1/2 × 0.021kg × 0.0036m²
I = 3.78 × 10⁻⁵ kgm²
Therefore, the moment of inertia for rotation about the perpendicular axis through the edge of the disk is 3.78 × 10⁻⁵ kgm².
