Area = r^2 * 3.14
87.9/3.14 = around 28
Square root of 28 = 5.3
The radius is 5.3
Circumference: diameter * 3.14
5.3 + 5.3 = 10.6
10.6 * 3.14 = 33.3
The circumference is 33.3
In order to accomplish that trick, we would need two pieces
of information that you haven't given us:
1). The area you're interested in
2). The population inside that area
With that information, the population density is
(population in the area) divided by (the area of the area) .
Well for this you can use simple multiplication or you can do a table like this
38.99. keep in mind to go through the
× 82. 2 first before going to 8
______
7798 make sure to add a zero for
+311920 each time you go down
_______
319718.
so you have you're answer but you have to make sure you put your decimal back so since it was in two places move the decimal to the left 2 times then you have your answer
answer- $3,197.18
