How could i make a circle in a graph formula? I'w never worked with graps.
+23254 If you want a circle with the center at (0,0) and a radius of r, use: x2 + y2 = r2.
For instance, a cricle with its center at the origin and a radius of 5: x2 + y2 = 52 or x2 + y2 = 25.
If you don't want the center at (0,0) then use the formula (x - h)2 + (y - k)2 = r2 where the center is (h, k).
For instance, a circle with its center at (4, -3) and radius = 7: (x - 4)2 + (y - -3)2 = 72 or:
(x - 4)2 + (y + 3)2 = 49.
