Answer:
2079
Step-by-step explanation:
Homes without children outnumbers homes with children by about 7 to 5 ;
If number of children = 3564
Number of homes without children :
Expressing the relaship interms of ratio :
Without children : with children = 7 :5
Total ratio = 7 + 5 = 12
Number of homes without children:
(7 / 12) * 3564
0.5833333 * 3564
= 2079
Radius, r = 939 ft
Then:
Diameter, d = 1878 ft
Circumference, C = 5899.9110034416 ft
Area, A = 2770008.2161158 ft^2
AREA = 2770 if you're shortening.
