Hey there! :D

Area= πr^2

So, the radius is half the diameter.

14/2= 7

7^2= 49

49π <== the answer

I hope this helps!

About 1.75 million people live in a circular region with a 15-mile diameter. Find the population density in people per square mi

pav-90 [236]

About 1.75 million people live in a circular region with a 15-mile diameter. Find the population density in people per square mile.

Solution: We are given that the population of a circular region = 1.75 million = $1,075,000$

Also we are given the circular region has a diameter = 15 mile

Which means the radius of region $\frac{15}{2}=7.5$ mile

Therefore, the area of the circular region $=\pi r^{2}$

$=3.14 \times 7.5^{2}$

$=176.625$

Now the population density per square mile is:

$\frac{1075000}{176.625}$

$6086.34 \approx6086$

Therefore, the population density per square mile is 6086

What is the answer plz help.

Dima020 [189]

Answer:

0.2

Step-by-step explanation:

C.O.P-the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.

So to find that you would divide y by x.

In this case the dot is between 0 and 2 on y so it is 1 and between 4 and 6 on x so it is 5.

Then you would divide 1/5 and get 0.2 or you could look at the end of the graph and notice that the last point is at (10,2) and divide 2/10 and get the same thing.

HOPE THIS HELPS!!!
