Answer:

<u>The diameter of this circle is equal to 8</u>

Step-by-step explanation:

The standard form of a circle is equal to x^2 + y^2 = r^2. As this equation shows x^2 + y^2 = 16, all we have to do is find the square root of 16, which is 4. This means that 4 is the radius of the circle and that 2 * 4 = 8, which is the diameter of the circle.

<u>Because of this, the diameter of this circle is equal to 8.</u>

Rzqust [24]

Given parameters:

Current population  = 530,300 people

Growth rate  = 0.8% per year

Unknown

Population in 15 more years  = ?

To solve this problem, we  must compound the increase per year.

This implies that we treat the problem like that of a compound interest.

Since we know that population increases by 0.8%,

                          it is similar to 1 + \frac{0.8}{100}  = 1.008 increase

Now the population in 15years will be;

                530300 x (1.008)¹⁵  = 597626 people

So, the population after 15yrs is 597626 people
