There are many ways to do this, I prefer the distance formula it looks like this:
We are given 2 pairs of coordinates: (0,2) and (0,4)
0=x1
2=y1
0=x2
4=y2
We take the numbers and sub in the values above in place of the variables:
Simplfy it:
0^2=0
2^2=4
We are left with :
Final answer: 2

Answer:
2.5 km
Step-by-step explanation:
First, find the area of the region:
- A circular region has a population of about 15,500 people;
- A population density of about 775 people per square kilometer.
So, there are square kilometers.
Now, let x kilometers be the radius of the circular region, then
To the nearest tenth this is 2.5 km.
