WebA circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle. Arcs are divided into minor arcs (0° < v < 180°), major arcs (180° < v < 360°) and semicircles (v = 180°). The length of an arc, l, is determined by plugging the degree measure of the ...

WebRadius of Circle Equation. The radius of a circle equation on the cartesian plane with center (h, k) is given as (x − h) 2 + (y − k) 2 = r 2. This is known as the equation of a circle when the radius is known. Here, (x, y) are the points on the circumference of the circle that is at a distance ‘r’ (radius) from the center (h, k).
A 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 … See more Put a pin in a board, put a loop of string around it, and insert a pencil into the loop. Keep the string stretched and draw the circle!
