Definition of Circle. Definition : A circle is the set of all points that are the same distance, r, from a fixed point. General Formula: X 2 + Y 2 =r 2 where r is the radius... Circular segment - is an area of a circle which is "cut off" from the rest of the circle by a secant (chord). On the picture: L - arc length h- height c- chord R- radius a- angle. If you know radius and angle you may use the following formulas to calculate remaining segment parameters: Circular segment formulas. Area: [1] Arc length: Chord length: Segment height: Circular segment. Radius

About "Using circumference to find radius" Given the circumference of a circle, we can use the appropriate circumference formula to find the radius or the diameter of the circle. We can use that information to solve problems.... The center of the incircle of a triangle is located at the intersection of the angle bisectors of the triangle. Given the side lengths of the triangle, it is possible to determine the radius of the circle. First, form three smaller triangles within the triangle, one vertex as the center of the incircle and the others coinciding with the vertices of the large triangle. Then, drop an altitude

Figure 1 is a circle with the center, radius, and diameter identified. The center is a fixed point in the middle of the circle; usually given the general coordinates (h, k). The fixed distance from the center to any point on the circle is called the radius .... Use the distance formula: Ans C. Circles A circle is the set of points a ﬁxed distance from a center : By the distance formula, 2. Eliminating the radical, we get: Equation of Circle in Standard Form: Note: is called the radius of the circle. D. Examples Example 1: Find the equation of a circle with center and radius . Solution The equation of a circle in standard form: Thus, we have: Ans
