To find out the center and the radius, we need to put the equation into the form (x – h)2 + (y – k)2 = r2. The skill needed to do that is one that we’ve used before: completing the square. Specifically, we need to do that twice, once to make the (x – h)2 and once to make the (y – k)2.

A curve is a part of the arc of a circle. It is limited at each end by the radii of the circle which form a central angle at the center of the circle. Curves are described by the following terms: A. Radius is the distance from a point on the curve to the center of the circle. B. Length. of curve is the linear measurement of the curve. C. Concavity

The standard form of a circle with radius “r” and centered at (h, k) is Eg. Write the equation of a circle with a radius of 8 units that has been translated 5 units to the right and 1 unit down from its standard position (ie. Center at origin). GENERAL FORM results when standard form is expanded. Eg. (x – 5)2 + (y + 1)2 = 64. Multiply this out and set it equal to zero. (Use FOIL) Remember, general form is written as
