Answer:

2 1/3 acres per hour

Step-by-step explanation:

If you divide both numbers by 2, you get 1/3 and 1/7. If 7 makes up an hour, then you multiply 1/3 by 7, which gets you 2.333.. which is equivalent to 2 1/3.

About 1.2 million people live in a region with a 6-mile radius what is the population destiny in people per square mile
Paladinen [302]

Answer:

10616 people per square mile

Step-by-step explanation:

No. of people living in the region = 1.2 million

Radius of the area = 6 mile

Since radius of region is given, area of can be calculated by using formula to get area of circle which is \pi r^2 where r is radius of circle.

the value of pie is 3.14 which will be used in the calculation

Area of region

\pi r^2    \\=> 3.14 * 6^2\\=> 113.04

population density of any place is calculated by dividing the total population of region with area of the region

mathematically it can be written as

population density of any place = the total population of region / area of the region

substituting the value of  total population of region with 1.2 million and  area of the region as calculated 113.04 square mile we have

population density of any place = 1.2 million/113.04 square mile

 = 0.0106157113 million / square mile

Since one million is equal to 1,000,000

0.0106157113 million will be equal to 0.0106157113 * 1,000,000

= 10615.7113

rounding 10615.7113 nearest to unit value, it will be 10616.

Therefore, population density is 10616 people per square mile.
