Write the standard equation of the circle in the graph.

a. (x + 3)squared + (y - 2)squared = 9
b. (x - 3)squared + (y + 2)squared = 9
c. (x - 3)squared + (y + 2)squared = 18
d. (x + 3)squared + (y - 2)squared = 18

B.

Step-by-step explanation:

From the given graph, it can be seen that the center of circle lies at (3,-2).

Radius = distance from the center to the boundary of circle.

=|3-0|=3 units

Standard equation of circle :

, where (h,k) is center and r is the radius of the circle.

Then , standard equation of the circle in the graph (having center (3,-2) and radius = 3 units)

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can
