Accepted Solution
A:
Answer:=0.3 per km²Step-by-step explanation:Population density is the population per uni area.Area=πr² Where A is area and r is the radius of the circle.A=3.14×34=106.76km²Population density = Population/Area=32 antelopes/106.76 km²=0.3 per km²The population of antelopes within the given radius is 0.3 per km²
