It is given that we need to find the equation of the circle with centre (3, 4) and touches the straight line 5x + 12y – 1 = 0.
Since, circle with centre (3, 4) and having a radius 62/13.
As, the equation of the circle with centre (p, q) and having radius ‘r’ is given by: (x – p)2 + (y – q)2 = r2
substituting the values in the equation, we get
∴ The equation of the circle is 169x2 + 169y2 – 1014x – 1352y + 381 = 0.
