a circular region has a population of about 44600 people and a population density of 388 people per square kilometer. what is the radius of the region?

18.85 miles

Step-by-step explanation:

Given in the question that,

diameter of pond around which Lloyd is walking by his dog = 2 miles

To find,

distance Lloyd covered in 3 laps

First find the circumference of the pond

circumference of the pond = 2π(d/2)

                                               = 2π(2/2)

                                               = 2π(1)

                                               = 2π

distance Lloyd travel in 1 lap = 2π miles

distance Lloyd travel in 3 lap = 2π x 3 miles

                                                  = 6π miles

                                                  = 18.85 miles

So, Lloyd walk 18.85 miles when he makes 3 laps around the pond.
