Years ago my high school math teacher showed us how to find the center of a given circle using only a compass, nothing else. I can't remember how. I need to do it now. Does anyone have the answer?
The center of a circle is the point that is equidistant from all points on the circle's circumference. It is often denoted by the letter "O".
To find the center of a circle given its equation, you can use the formula (h, k), where "h" represents the x-coordinate of the center and "k" represents the y-coordinate. These can be found by rewriting the equation in the standard form (x-h)^2 + (y-k)^2 = r^2, where (h, k) is the center and "r" is the radius.
To find the center of a circle, you need to know either the coordinates of three points on the circumference of the circle or the equation of the circle.
No, you cannot find the center of a circle if you only know its radius. You also need to know either the coordinates of three points on the circumference of the circle or the equation of the circle.
The center of a circle lies on the midpoint of its diameter. This means that the distance from the center to any point on the circle's circumference is equal to half of the diameter.
