Graphs of Circles Worksheets
How to Determine Equation of Circle - A Circle is a certain shape and that has a set of points in a plane placed at equal distance from a single point called the center of the circle. A circle is the locus of all points intermediate from a central point. A curved line that is fragment of the circumference of a circle or a line segment within a circle that touches 2 points on the circle. The circle equation of the center radius form is in this format (x – h)2 + (y - k)2 = r2, With the center being at the point (h & k) and the radius being "r". This form of the equation is useful, since you can easily find the center and the radius. We use the circle formula to calculate the area, diameter, and circumference of a circle. The length between any point on the circle is known as its radius. Any line that passes through the center of the circle and connects two points is known as the diameter of the circle. Radius is half the length of a diameter of the circle. Thea area of the circle describes the amount of space covered by the circle and the length of the boundary of the circle is known as its circumference.
