The center is
the radius is units.

The center is at

3 units

Step-by-step explanation:

You can observe in the graph a circle.

The x-coordinate and the y-coordinate of the center of the circle shown in the figure are:

and

Therefore, the point of the center of the circle is:

 You can observe that the diameter goes from -1 to 5, then the diameter is:

The radius is half the diameter. Therefore, you can say that the radius of this circle is:

ANSWER

The center is (2,4)

The radius is 2√2 units

EXPLANATION

Each of the ticks is 1 unit

Counting two ticks from the origin to the right and 4 units up will land us at the center of the circle.

Hence the center is (2,4)

The circle passes through (0,2).

The radius is

1/5^2 = 7.56/45

d is correct
