We need to know the density of Marble City, hence we know the density of Pebble City. MC density = population/area MC density = 52,348/125 MC density = 418.784 people/miles
From the question, we know that the two cities have the same population density. PC density = MC density PC density = 418.784 people/miles
Use the density formula to figure out the dimension of PC PC density = population/area 418.784 = 85,312/(l × w) (l × w) = 85,312/418.784 11.8 w = 85,312/418.784 11.8 w = 203.7 w = 203.7/11.8 w = 17.2
We know that <span>Since a circle is 360 degrees, then 360</span>°-----------> 100% <span>x </span>°----------> <span>15% </span>x=15*360/100-----> x=54°
