-- Draw any two random chords of the circle.
-- Construct the perpendicular bisector of each chord.
-- The perpendicular bisectors intersect at the center of the circle.
All of this can be done with a compass, an unmarked straight-edge, and a pencil.

R (radius) X2. The radius is half the circle from the center of the circle. The diameter is just straight across.
Center.
Endpoints of diameter: (-10, -2) and (4, 6)Midpoint which is the center of the circle: (-3, 2)Radius of the circle: square root of 65Equation of the circle: (x+3)^2 +(y-2)^2 = 65
yes a diameter passes through the center of a circle
