Answer:
The population density is 618.93 per square mile.
Step-by-step explanation:
It is given that,
No. of people, N = 70,000
The radius of a city's town hall, r = 6 miles
We need to find the population density. It can be calculated by the formula i.e. number of people divided by area of land such that,
![P=\dfrac{N}{A}\\\\P=\dfrac{N}{\pi r^2}\\\\P=\dfrac{70000}{\pi (6)^2}\\\\P=618.93\ \text{per square mile}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BN%7D%7BA%7D%5C%5C%5C%5CP%3D%5Cdfrac%7BN%7D%7B%5Cpi%20r%5E2%7D%5C%5C%5C%5CP%3D%5Cdfrac%7B70000%7D%7B%5Cpi%20%286%29%5E2%7D%5C%5C%5C%5CP%3D618.93%5C%20%5Ctext%7Bper%20square%20mile%7D)
So, the population density is 618.93 per square mile.
Answer:
There are 10 squares present in this picture
Answer:
D
Step-by-step explanation:
Im almost positive its d because for triangles you multiply by radical two for when its 45 degrees then the side for the one part of the triangle would be 26 radical 2 multiplied by 39 to get 1397.243 then you double that to get d
