This is the form of a circle. Use this form to determine the center and radius of the circle. (x-h)^2+(y-k)^2=r^2 Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from t...
To find the center and radius of a circle, you need either the equation of the circle or three points that lie on the circle. With the equation, you can use the formula (h,k) for the center and r for the radius. With three points, you can use the distance f...

Where is the radius of a circle? The radius of a circle is the line segment from the center of a circle to a point on the boundary of a circle. Is a radius half of a diameter? Yes, the radius of a circle is half of the diameter because the diameter is the line segment that pas...
Because all circles have the same shape, their different measurements are related by a set of simple equations. If you know the radius, diameter, area or circumference of a circle, it is fairly easy to find any of the other measurements.
