Answer:
<u>A) 19.66 people/km²</u>
Step-by-step explanation:
<u>Given</u>
- Area of the continent = 1.78 x 10⁷ km²
- Population = 3.5 x 10⁸ people
<u>To Find</u>
<u>Solving</u>
- population density is the number of people per unit area
- pd = people / area
- pd = 3.5 x 10⁸ / 1.78 x 10⁷
- pd = 1.966 x 10
- pd = <u>19.66 people/km²</u>
Given: A cylinder with radius = 10 inches and height = 6 inches.
We have to determine the volume of the cylinder.
Volume of a cylinder with radius 'r' and height 'h' is given by the formula 
Substituting the value of 'r' and 'h', we get
Volume = 
Volume = 
Volume = 1884 cubic inches.
Therefore, the volume of the cylinder is 1884 cubic inches.
