Answer:
76 lizards per square miles
Step-by-step explanation:
We are given that The biologist counts 15 lizards within a radius of 14 mi of the boulder.
Area of boulder = [tex]\pi r^{2}[/tex]
= [tex]3.14 \times (\frac{1}{4})^{2}[/tex]
= [tex]0.19625[/tex]
Now [tex]Density = \frac{Mass}{Area}[/tex]
Mass = 15 lizards
Area = 0.19625 square miles.
So, population density = [tex]\frac{15}{0.19625}[/tex]
= [tex]76.433[/tex]
Hence the population density of lizards is 76 lizards per square miles
