WebCoordinates of a point on a circle. Looking at the figure above, point P is on the circle at a fixed distance r (the radius) from the center. The point P subtends an angle t to the positive x-axis. Click 'reset' and note this angle initially has a measure of 40°. Using trigonometry, we can find the coordinates of P from the right triangle shown.
WebDraw a circle around ( 2, 3) with radius 3. Any of the points on this circle could be the center of the circle you seek. Acoording to you ( x, y) is the centre with radius 3 . So by the distance formula ( x − 2) 2 + ( y − 3) 2 = 3 2 = 9. Then by plugging in any value for y you get a corresponding value for x.
