If the set of points have a constant distance (radius, r) from a point, the set of points form a circle, which has the standard equation:

(x-x0)^2+(y-y0)^2=r^2

where (x0,y0) is the given point (-2,-6), and r=radius=2.

Substituting, the equation is then
(x-(-2))^2+(y-(-6))^2=2^2, or

(x+4)^2+(y+6)^2=4......(1)

The location of four buildings on a coordinate grid are as follows:
Gre4nikov [31]

Answer:

3400 feet

Step-by-step explanation:

Distance between building 1 and building 2 = |5+3| = 8

Distance between building 2 and building 3 = |4+5| = 9

Distance between building 3 and building 4 = |-3-5| = 8

Distance between building 4 and building 1 = |4+5| = 9

total distance = 8 x 2 + 9 x 2 = 34

total distance in feet =  34 x 100 = 3400 feet
