The coordinates for the center were found by using the formula for the midpoint of a segment: You find the length of the diameter by using the distance formula: For the circle shown, the diameter is 10 units long. Next, you find the length of one of the radii. Either will do — they're the same length.
WebYou can draw two perpendicular lines along book's edge which intersect with the circle at two different points. Connect the two points and it's a diameter. Repeat this and get another diameter. The intersect of these two diameters is the center of the circle. Share Cite Follow edited Oct 4, 2012 at 19:03 Janaaaa 101 3 answered Oct 2, 2012 at 12:11
