What is the diameter of a circle (in units) with the center at {eq}(-5, 3) {/eq} and tangent to the line {eq}8 - 2x = 2 {/eq}? Radius of a Circle: We find a circle's radius by finding the distance between the center and the coordinate o...
Chord of a CircleA line segment joining two points on the circle is a chord. In other words, a chord is a segment whose endpoints are on the boundary of the circle. A chord usually divides a circle into two unequal halves unless the chord goes through the center of the circle. The ...
All those points for which the distance is equal to that of the radius of a circle lie on the circle. For example points U and V lie on the circle.Semicircle:Semi means half, so semicircle is half a circle. It is formed by cutting a whole circle along a line segment passing through...
