WebCircles are described mathematically by equations. Circle equations are presented here in all their forms, such as standard and general forms, with examples. Equation of a Circle When the Centre is Origin. Imagine an arbitrary point P(x, y) on the circle. Let ‘a’ be the radius of the circle that is equal to OP. Let us put a circle of radius 5 on a graph: Now let's work out exactlywhere all the points are. We make a right-angled triangle: And then use Pythagoras: x2 + y2 = 52 There are an infinitenumber of those points, here are some examples: In all cases a point on the circle follows the rule x2 + y2 = radius2 We … Meer weergeven Now let us put the center at (a,b) So the circle is all the points (x,y) that are "r" away from the center (a,b).
