By the end you'll easily be able to figure the center, and the radius. If not, use a calculator to find the square root of that number on the right side, then use the square root as the radius. A Find the center and radius of the circle. What is the equation of the circle pictured on the graph below.

Set up a truly inviting living room atmosphere through the tips we will give you below. This is called the center-radius form or standard form because it gives you both pieces of information at the same time. A circle is all of the points that are a fixed distance, known as the radius, from a given point, known as the center of the circle. We will review it through an example. Write the general form of a parabola in standard form. The variable v represents the vertical displacement how far above or below the center fall.

Secondly, turn the dial to the left counter-clockwise. The h and v represent the center of the circle at point h, v, and r names the radius. Explore the standard equation of a circle using the applet below Go here for a larger version. Here you'll be shown how to take the equation of a circle, and convert it into standard form.
