Formulas involving circles often contain a mathematical constant pi denoted as p. The standard form equation looks like this. The general form of equation of circle always has x2 y2 in the beginning.
In this we discuss about Properties of circle circle formulas like area perimeter arc length segment length segment area.
H and k are the x and y coordinates of the center of the circle x 9 2 y 6 2 100 is a circle centered at 9 6 with a radius of 10. The standard form of an equation of a circle is x - h 2 y - k 2 r 2. If a circle crosses both the axes then there are four points of intersection of the circle and the axes. If any equation is of the form x2 y2 axy C 0 then it is not the equation of the circle.
