Diameter of circle equation
WebA line that "just touches" the circle as it passes by is called a Tangent. A line that cuts the circle at two points is called a Secant. A line segment that goes from one point to another on the circle's circumference is called a Chord. If it passes through the center it is called a Diameter. And a part of the circumference is called an Arc. WebThe radius of the circle x 2 + y 2 − 2 x + 3 y + k = 0 is 2 2 1 . Find the value of k . Find also the equation of the diameter of the circle which passes through the point ( 5 , 2 2 1 ) .
