Answer:
<h2>C ≈ 12.56 m, A ≈ 12.56 m²</h2>Step-by-step explanation:
The formula of a perimeter (circumference) of a circle:
<em>d</em> - diameter
The formula of an area of a circle:
<em>r</em> - radius
We have <em>d = 2r = 4m → r = 2m.</em>
<em>Substitute:</em>
<em>Use π ≈ 3.14</em>
The population function of the Western Lowland Gorillas can either represent population growth or population decay
<h3>How to model the population</h3>The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.
So, I will give a general explanation to solve the question
A population function can be represented as:
Where:
- The initial population of the Western Lowland Gorillas is represented by (a)
- The rate at which the population changes is represented by (r)
- The number of years since 2022 is represented by (x)
- The population in x years is represented by (y)
From the question, we understand that the population of the Western Lowland Gorillas decreases.
This means that the rate of the function would be an exponential decay i.e. 1 -r
Take for instance:
By comparison.
a = 2000 and 1 - r = 0.98
The above function can be used to model the population of the Western Lowland Gorillas
