A circle has to points on the circumference (0, 1) and (0, 9) that bisect the circle and I have to give the equation of the circle in general form. So I can find the midpoint of the circle as ${(0...

A circle is easy to make: Draw a curve that is radius away from a central point. And so: All points are the same distance from the center. x2 + y2 = 52.

Nov 21, 2025 · Enter the coordinates of two points on the circle into the calculator to determine the center of the circle.

A circle, geometrically, is a simple closed shape. More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center.

Mar 13, 2018 · Step 1 Measure the circle's radius with a ruler, or record the figure given to you in the math problem. The radius of a circle measures the distance from the center to any point …

Nov 28, 2025 · Points on the circle can be found even without a compass, graph paper, or radius of the circle. Learn how to find points on the circle with equations here!

Now putting these three values in the first equation (A), we get the required equation of a circle passing through two points and with its center lying on the line.

A point (x, y) is at a distance r from the origin if and only if x 2 + y 2 = r, or, if we square both sides: x 2 + y 2 = r 2. This is the equation of the circle of radius r centered at the origin.
