The distance between a circle whose square of circle x + y equals 25 and a line whose square of circle x + y + 1 equals 0 is?

The distance between a circle whose square of circle x + y equals 25 and a line whose square of circle x + y + 1 equals 0 is?

If the center of the circle is (0,0), then the distance from the center of the circle to the straight line is d = | 1 | / radical (1 + 1) = 1 / radical 2 = radical 2 / 2
And radius r = 5
Then the maximum distance from a point on a circle to a straight line is R + radical 2 / 2 = 5 + radical 2 / 2, and the minimum distance is r-radical 2 / 2 = 5-radical 2 / 2
