The center is O,
and the radius is

center: (0,0)

radius: 4 units

Step-by-step explanation:

the circle goes through points (0,4), (0,-4), (4,0), and -4,0).

if you notice, all four points are 4 away from the origin, (0,0). this means that there center is (0,0).

if you start at one of the points and go to the origin, it will be 4 units. that will be your radius

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
