Question

The endpoints of the diameter of a circle have the coordinates (3,8) and (9,16) .

What are the coordinates of the center of the circle?

Answer 1

9514 1404 393

Answer:

(6, 12)

Explanation:

The center of the circle is the midpoint of the diameter, the average of the end point coordinates:

((3, 8) +(9, 16))/2 = (3+9, 8+16)/2 = (12, 24)/2 = (6, 12)

The center of the circle is (6, 12).
