How to determine if a point is in a circle

WebTo know that where does the given point lie in the circle, we have to find the length of tangent. Length of the tangent = √ (x₁² + y₁² + 2gx₁ +2fy₁ + c) Here x₁ = 7 and y₁ = -11 = √ x2 + y2 − 10x = √7 2 + (-11)2 − 10 (7) = √49 + 121 - 70 = √ 170 - 70 = √100 = 10 > 0 Hence the given point (7, -11) outside the circle. WebThe formula for a circle is (x−a)2 + (y−b)2 = r2 So the center is at (4,2) And r2 is 25, so the radius is √25 = 5 So we can plot: The Center: (4,2) Up: (4,2+5) = (4,7) Down: (4,2−5) = …
