Take the point (1,0) as the center and 3 as the radius to draw a circle, then the coordinates of the intersection of the circle and the X axis are______ The coordinates of the point of intersection with the y-axis are_________
(- 2,0) (4,0) (0,2.84) (0, - 2.84) 2.84 is the divisor of the root of 8! I can't type the root on my mobile phone, sorry!
Take point P (0,2) as the center of the circle, take 3 as the radius to draw the circle, and write out the coordinates of the intersection of the circle and the Y axis
Because the center of the circle is on the Y axis, the ordinates are 2 + 3 and 2-3
That is (0,5) (0, - 1)
Take (3,0) as the center and 2 as the radius to draw a circle, then the intersection coordinate of the circle and X axis is______ .
The coordinates of the intersection of the circle and the x-axis are (3-2, 0) (3 + 2, 0), namely (1, 0), (5, 0)
Take the point (4,0) as the center of the circle and 2 as the radius to draw a circle, then the intersection coordinate of the circle and the X axis is_______
Hello
The intersection points are (2,0) and (6,0)
